-PHP Coding Standards
-====================
-
-
-This file lists several standards that any programmer, adding or changing
-code in PHP, should follow.  Since this file was added at a very late
-stage of the development of PHP v3.0, the code base does not (yet) fully
-follow it, but it's going in that general direction.  Since we are now
-well into the version 4 releases, many sections have been recoded to use
-these rules.
-
-
-Code Implementation
-------------------
-
-[1] Functions that are given pointers to resources should not free them
-
-For instance, function int mail(char *to, char *from) should NOT free
-to and/or from.
-Exceptions:
-
-  - The function's designated behavior is freeing that resource.  E.g. efree()
-  - The function is given a boolean argument, that controls whether or not
-    the function may free its arguments (if true - the function must free its
-    arguments, if false - it must not)
-  - Low-level parser routines, that are tightly integrated with the token
-    cache and the bison code for minimum memory copying overhead.
-    
-[2] Functions that are tightly integrated with other functions within the
-    same module, and rely on each other non-trivial behavior, should be
-    documented as such and declared 'static'.  They should be avoided if
-    possible.
-
-[3] Use definitions and macros whenever possible, so that constants have
-    meaningful names and can be easily manipulated.  The only exceptions
-    to this rule are 0 and 1, when used as false and true (respectively).
-    Any other use of a numeric constant to specify different behavior
-    or actions should be done through a #define.
-
-[4] When writing functions that deal with strings, be sure to remember
-    that PHP holds the length property of each string, and that it
-    shouldn't be calculated with strlen().  Write your functions in a such
-    a way so that they'll take advantage of the length property, both
-    for efficiency and in order for them to be binary-safe.
-    Functions that change strings and obtain their new lengths while
-    doing so, should return that new length, so it doesn't have to be
-    recalculated with strlen() (e.g. php_addslashes())
-
-[5] Use php_error() to report any errors/warnings during code execution.
-    Use descriptive error messages, and try to avoid using identical
-    error strings for different stages of an error.  For example,
-    if in order to obtain a URL you have to parse the URL, connect,
-    and retreive the text, assuming something can go wrong at each
-    of these stages, don't report an error "Unable to get URL"
-    on all of them, but instead, write something like "Unable
-    to parse URL", "Unable to connect to URL server" and "Unable
-    to fetch URL text", respectively.
-
-[6] NEVER USE strncat().  If you're absolutely sure you know what you're doing,
-    check its man page again, and only then, consider using it, and even then,
-    try avoiding it.
-
-
-Naming Conventions
------------------
-
-[1] Function names for user-level functions should be enclosed with in
-    the PHP_FUNCTION() macro. They should be in lowercase, with words
-    underscore delimited, with care taken to minimize the letter count.
-    Abbreviations should not be used when they greatly decrease the
-    readability of the function name itself.
-
-    Good:
-    'mcrypt_enc_self_test'
-    'mysql_list_fields'
-
-    Ok:
-    'mcrypt_module_get_algo_supported_key_sizes'
-    (could be 'mcrypt_mod_get_algo_sup_key_sizes'?)
-    'get_html_translation_table'
-    (could be 'html_get_trans_table'?) 
-
-    Bad:
-    'hw_GetObjectByQueryCollObj'
-    'pg_setclientencoding'
-    'jf_n_s_i'
-    
-    
-[2] If they are part of a "parent set" of functions, that parent should
-    be included in the user function name, and should be clearly related
-    to the parent program or function family. This should be in the form
-    of parent_*.
-    
-    A family of 'foo' functions, for example:
-    Good:
-    'foo_select_bar'
-    'foo_insert_baz'
-    'foo_delete_baz'
-
-    Bad:
-    'fooselect_bar'
-    'fooinsertbaz'
-    'delete_foo_baz'
-
-[3] Function names used by user functions should be prefixed
-    with "_php_", and followed by a word or an underscore-delimited list of
-    words, in lowercase letters, that describes the function.  If applicable,
-    they should be declared 'static'.
-    
-[4] Variable names must be meaningful.  One letter variable names must be
-    avoided, except for places where the variable has no real meaning or
-    a trivial meaning (e.g. for (i=0; i<100; i++) ...).
-
-[5] Variable names should be in lowercase.  Use underscores to separate
-    between words.
-
-
-Syntax and indentation
----------------------
-
-[1] Never use C++ style comments (i.e. // comment).  Always use C-style
-    comments instead.  PHP is written in C, and is aimed at compiling
-    under any ANSI-C compliant compiler.  Even though many compilers
-    accept C++-style comments in C code, you have to ensure that your
-    code would compile with other compilers as well.
-    The only exception to this rule is code that is Win32-specific,
-    because the Win32 port is MS-Visual C++ specific, and this compiler
-    is known to accept C++-style comments in C code.
-
-[2] Use K&R-style.  Of course, we can't and don't want to
-    force anybody to use a style he or she is not used to, but,
-    at the very least, when you write code that goes into the core
-    of PHP or one of its standard modules, please maintain the K&R
-    style.  This applies to just about everything, starting with
-    indentation and comment styles and up to function declaration
-    syntax.
-    
-[3] Be generous with whitespace and braces.  Always prefer:
-
-	if (foo) {
-		bar;
-	}
-
-	to:
-
-	if(foo)bar;
-
-    Keep one empty line between the variable declaration section and
-    the statements in a block, as well as between logical statement
-    groups in a block.  Maintain at least one empty line between
-    two functions, preferably two.
-
-[4] When indenting, use the tab character.  A tab is expected to represent
-    four spaces.  It is important to maintain consistency in indenture so
-    that definitions, comments, and control structures line up correctly.
-
-Documentation and Folding Hooks
-------------------------------
-
-In order to make sure that the online documentation stays in line with
-the code, each user-level function should have its user-level function
-prototype before it along with a brief one-line description of what the
-function does.  It would look like this:
-
-/* {{{ proto int abs(int number)
-   Returns the absolute value of the number */
-PHP_FUNCTION(abs)
-{
-   ...
-}
-/* }}} */
-
-The {{{ symbols are the default folding symbols for the folding mode in
-Emacs and vim (set fdm=marker).  Folding is very useful when dealing with 
-large files because you can scroll through the file quickly and just unfold 
-the function you wish to work on.  The }}} at the end of each function marks 
-the end of the fold, and should be on a separate line.
-
-The "proto" keyword there is just a helper for the doc/genfuncsummary script
-which generates a full function summary.  Having this keyword in front of the
-function prototypes allows us to put folds elsewhere in the code without
-messing up the function summary.
-
-Optional arguments are written like this:
-
-/* {{{ proto object imap_header(int stream_id, int msg_no [, int from_length [, int subject_length [, string default_host]]])
-   Returns a header object with the defined parameters */
-
-And yes, please keep the prototype on a single line, even if that line
-is massive.
-
-New and Experimental Functions
-----------------------------------
-To reduce the problems normally associated with the first public
-implementation of a new set of functions, it has been suggested
-that the first implementation include a file labeled 'EXPERIMENTAL'
-in the function directory, and that the functions follow the
-standard prefixing conventions during their initial implementation.
-
-The file labelled 'EXPERIMENTAL' should include the following
-information:
-   Any authoring information (known bugs, future directions of the module).
-   Ongoing status notes which may not be appropriate for CVS comments.
-
-Aliases & Legacy Documentation
-----------------------------------
-You may also have some deprecated aliases with close to duplicate
-names, for example, somedb_select_result and somedb_selectresult. For
-documentation purposes, these will only be documented by the most
-current name, with the aliases listed in the documentation for
-the parent function. For ease of reference, user-functions with
-completely different names, that alias to the same function (such as
-highlight_file and show_source), will be separately documented. The
-proto should still be included, describing which function is aliased.
-
-Backwards compatible functions and names should be maintained as long
-as the code can be reasonably be kept as part of the codebase. See
-/phpdoc/README for more information on documentation.

-Installation Instructions for PHP 4.0
-------------------------------------
-
-For the impatient here is a quick set of steps that will build PHP as
-first a dynamic Apache module (DSO) for Apache 1.3.x with MySQL support 
-and then a static module.  A more verbose explanation follows.  
-
-For installing PHP on other web servers, refer to one of the following
-files:
-
-    sapi/aolserver/README
-    sapi/pi3web/README
-    sapi/servlet/README
-    sapi/thttpd/README
-    README.Zeus
-
-Note!  Only install either the static module or the dynamic one.  Do not
-install both.  
-
-Note 2!  If you are recompiling PHP to add new extensions or upgrading
-something like GD, remove the config.cache file before you re-run 
-configure.
-
-Note 3!  If you are on Linux and have installed shared libraries, make
-sure the location of these shared libraries are listed in your 
-/etc/ld.so.conf file.  For example, if you have:
-
-  /usr/local/lib/mysql/libmysqlclient.so
-
-Make sure /etc/ld.so.conf contains:
-
-  /usr/local/lib/mysql
-
-Then run ldconfig.
-
-If you want both PHP 3 and 4 modules in the same Apache server, check the
-bottom of this file for instructions.
-
-INSTALLATION WITH THE ZEUS WEB SERVER:
--Please see the 'README.Zeus' file included in this distribution
-
-
-QUICK INSTALL (DSO)
-
-For this to work your Apache httpd must have mod_so enabled.
-Check using httpd -l.  You should see something like:
-
-Compiled-in modules:
-  http_core.c
-  mod_so.c
-
-Chances are you will see a lot more modules than these two. That's ok, 
-as long as mod_so.c shows up you can proceed with the following steps:
-
-$ gunzip -c php-4.0.x.tar.gz | tar xf -
-$ cd php-4.0.x
-$ ./configure --with-mysql --with-apxs
-$ make
-$ make install
-
-If you get an error telling you that the apxs script could not be found,
-look for it on your system and if you find it, provide the full path to it
-as: --with-apxs=/path/to/apxs
-
-Next you must copy php.ini-dist to the appropriate place (normally
-/usr/local/lib/php.ini) and edit it as necessary to set PHP options.
-
-The only thing left to do is to edit your httpd.conf file and make sure the
-PHP 4 mime type is there and uncommented.  You need a line that looks like
-this:
-
-   AddType application/x-httpd-php .php
-
-Then restart your server (apachectl restart) and you should be able to
-serve up PHP files now.  Make a test file called test.php and put some 
-PHP tags in it.  Like <?phpinfo()?>, for example.
-
-
-QUICK INSTALL (Static)
-
-$ gunzip -c apache_1.3.x.tar.gz | tar xf -
-$ cd apache_1.3.x
-$ ./configure
-$ cd ..
-
-$ gunzip -c php-4.0.x.tar.gz | tar xf -
-$ cd php-4.0.x
-$ ./configure --with-mysql --with-apache=../apache_1.3.x --enable-track-vars
-$ make
-$ make install
-
-$ cd ../apache_1.3.x
-$ ./configure --prefix=/www --activate-module=src/modules/php4/libphp4.a
- (The above line is correct!  Yes, we know libphp4.a does not exist at this
-  stage.  It isn't supposed to.  It will be created.)
-$ make
- (you should now have an httpd binary which you can copy to your Apache bin dir if
-  is is your first install then you need to "make install" as well)
-$ cd ../php-4.0.x
-$ cp php.ini-dist /usr/local/lib/php.ini
-You can edit /usr/local/lib/php.ini file to set PHP options.
-Edit your httpd.conf or srm.conf file and add:
-  AddType application/x-httpd-php .php
-
-
-VERBOSE INSTALL
-
-Chances are you are reading this because the quick install steps above
-did not work for you.  If this is the case, congratulations, you are
-among the elite few that actually reads documentation.  It really is
-not a difficult install and once you have done it once you will fly 
-through it.
-
-Installing PHP can be done in four simple steps:
-
-1. Unpack your distribution file.  
-
-   You will have downloaded a file named something like php-4.0.x.tar.gz.
-   Unzip this file with a command like: gunzip php-4.0.x.tar.gz
-
-   Next you have to untar it with: tar -xvf php-4.0.x.tar
-
-   This will create a php-4.0.x directory.  cd into this new directory.
-
-2a. Configure PHP (Dynamic Module) - Skip to 2b if you wish to build
-    a static module
-
-   You now have to choose the options you would like.  There are quite
-   a few of them.  To see a list, type: ./configure --help
-
-   The only options that you are likely to want to use are the ones in
-   the last section entitled, "--enable and --with options recognized:"
-
-   A popular choice is to build the Apache module version.  In order to
-   build PHP as a dynamic module for Apache-1.3.x you have to first have
-   Apache installed.  Assuming Apache is already installed, make sure
-   the shared object module is enabled.  To check this, type: httpd -l
-   You should see something like:
-
-     Compiled-in modules:
-       http_core.c
-       mod_so.c
-
-   You will most likely have a lot more modules than what is shown here.
-   As long as mod_so.c shows up in the list, PHP should be happy.
-
-   Now, type: ./configure --with-mysql --with-apxs
-
-   If you get an error telling you that the apxs script could not be found,
-   look for it on your system and if you find it, provide the full path to it
-   as: --with-apxs=/path/to/apxs
-
-   You might also want other flags on this configure line.  --with-mysql
-   is just an example.  
-
-   There are a few things that can go wrong during this configure step.
-   The most common is that you have asked for an option and that the
-   configure script can not find the files required to enable this 
-   option in PHP.  Chances are you can provide the full path to the
-   base directory under which the related files were installed.  For
-   example, if you have installed the GD library in /opt/gd which means
-   that /opt/gd/include has your GD header files and /opt/gd/lib contains
-   your GD library files, you would use --with-gd=/opt/gd
-
-   Skip to step 3 for compilation and installation instructions.
-
-2b. Configure PHP (Static Module) - Skip if you performed 2a
-
-   You now have to choose the options you would like.  There are quite
-   a few of them.  To see a list, type: ./configure --help
-
-   The only options that you are likely to want to use are the ones in
-   the last section entitled, "--enable and --with options recognized:"
-
-   A popular choice is to build the Apache module version.  You need
-   to know where the source code directory for your Apache server is
-   located.  Then use an option like: --with-apache=/usr/local/src/apache
-   if that is your Apache source code directory.  If you only specify
-   --with-apache, then it will default to look for your Apache source 
-   in /usr/local/etc/httpd.
-
-   NOTE: The directory you specify should be the top-level of the
-   unpacked Apache (or Stronghold) distribution. The configure program
-   will automatically look for httpd.h in different directories under that
-   location depending on which version of Apache, including Stronghold,
-   you are running.
-
-   For MySQL support, since newer versions of MySQL installs its various
-   components under /usr/local, this is the default.  If you have
-   changed the location you can specify it with: --with-mysql=/opt/local
-   for example.  Otherwise just use: --with-mysql
-
-   *NOTE*  If you are using Apache 1.3b6 or later, you should run the 
-   Apache Configure script at least once before compiling PHP.  It 
-   doesn't matter how you have Apache configured at this point.
-
-   Skip to step 3b at this point.
-
-3. Compile and install the files.  Simply type: make install
-
-3a.   Dynamic Module Installation
-
-   Nothing else is needed here.  Proceed to step 4a.
-
-3b.   Static Module Installation
-
-   For the Apache module version this will copy the appropriate files
-   to the src/modules/php4 directory in your Apache distribution if
-   you are using Apache 1.3.x.  If you are still running Apache 1.2.x
-   these files will be copied directly to the main src directory.
-
-   For Apache 1.3b6 and later, you can use the new APACI configuration
-   mechanism.  To automatically build Apache with PHP support, use:
-
-       cd apache_1.3.x
-       ./configure --prefix=/<path>/apache \
-                   --activate-module=src/modules/php4/libphp4.a
-       make
-       make install
-
-   If you do not wish to use this new configuration tool, the old
-   install procedure (src/Configure) will work fine.
-
-   If you are using the old Apache ./Configure script, you will have to 
-   edit the Apache src/Configuration file manually.  If you do not have 
-   this file, copy Configuration.tmpl to Configuration.
-
-   For Apache 1.3.x add:
-
-      AddModule modules/php4/libphp4.a
-
-   For Apache 1.3.x don't do anything else.  Just add this line and then
-   run "./Configure" followed by "make".
-
-   For Apache 1.2.x add:
-
-      Module php4_module mod_php4.o
-
-   For Apache 1.2.x you will also have to look in the libphp4.module file,
-   which was copied to the src directory. The EXTRA_LIBS line in the Apache
-   Configuration file needs to be set to use the same libs as specified on
-   the LIBS line in libphp4.module. You also need to make sure to add
-   "-L." to the beginning of the EXTRA_LIBS line.
-
-   So, as an example, your EXTRA_LIBS line might look like:
-
-	EXTRA_LIBS=-L. -lphp4 -lgdbm -ldb -L/usr/local/mysql/lib -lmysqlclient
-
-   NOTE: You should not enclose the EXTRA_LIBS line in double-quotes, as it
-   is in the libphp4.module file.
-
-   Also, look at the RULE_WANTHSREGEX setting in the libphp4.module file 
-   and set the WANTHSREGEX directive accordingly in your Configuration file.
-   This last step applies to versions of Apache prior to 1.3b3.
-
-   This is a bit of a hassle, but should serve as incentive to move to
-   Apache 1.3.x where this step has been eliminated.
-
-   Once you are satisfied with your Configuration settings, type: ./Configure
-   If you get errors, chances are that you forgot a library or made a typo
-   somewhere.  Re-edit Configuration and try again.  If it goes well,
-   type: make
-
-   Assuming it compiles without errors, proceed to step 4b.
-
-4a. Setting up the server. (Dynamic Module)
-
-   The make install command in step 3 should have done most of your
-   work for you.  It actually edits your httpd.conf file and tries to
-   enable the dynamic PHP module.  To verify this, look for a line that
-   looks like this:
-
-      LoadModule php4_module libexec/libphp4.so
-
-   The actual path before the libphp4.so part might differ slightly.  This
-   is likely fine.  If you are paranoid you can examine the output from the
-   make install step to see where the libphp4.so file was actually put and
-   place the full path to this file on this LoadModule line.
-
-   If somewhere in your httpd.conf file you have a ClearModuleList line
-   then you also need this line:
-
-      AddModule mod_php4.c
-
-   And finally you need to tell Apache which file extension should trigger
-   PHP.  You do this by creating a special mime type and associating it
-   with an extension.  We suggest using:
-
-      AddType application/x-httpd-php .php
-  
-   You are however free to use any extension you wish, including .html.
-
-   Note!  If a line has a # at the beginning, then it is commented out
-   and you need to remove the # for that line to take effect.
-
-   Finally you need to copy php.ini-dist to the appropriate place
-   (normally /usr/local/lib/php.ini) and edit if necessary.
-
-   Once you have made these changes you should be ready to restart your
-   server and try it out.  Type: apachectl restart
-   
-4b. Setting up the server. (Static Module)
-   
-   You should now have a new httpd binary.  Shut down your existing server,
-   if you have one, and copy this new binary overtop of it.  Perhaps make
-   a backup of your previous one first.  Then edit your conf/httpd.conf file
-   and add the line:
-
-      AddType application/x-httpd-php .php
-
-   There is also an interesting feature which can be quite instructive and
-   helpful while debugging.  That is the option of having colour syntax
-   highlighting.  To enable this, add the following line:
-
-      AddType application/x-httpd-php-source .phps
-
-   Any file ending in .phps will now be displayed with full colour syntax
-   highlighting instead of being executed.
-
-   Note that on some older server setups, the AddType lines are in the
-   conf/srm.conf file instead of conf/httpd.conf.
-
-   Note!  If a line has a # at the beginning, then it is commented out
-   and you need to remove the # for that line to take effect.
-
-   When you are finished making changes to your httpd.conf file, you need
-   to copy php.ini-dist to the appropriate place (normally
-   /usr/local/lib/php.ini) and edit if necessary. You can then
-   start up your server.
-
-5. Testing it all worked
-
-   Create a test file named test.php in your web tree somewhere and
-   put some test PHP tags in it.  <?phpinfo()?> is a good first test.
-   This tag tells PHP to do a braindump and tells you all sorts of things
-   about itself.

-WHY DISABLING -fPIC WORKS ON LINUX

-

-
-    Correct, depending on the meaning of "relocatable". PIC code typically
-    does not contain relocations; that's why its position-independent.
-
-    > Just because you don't specify -fPIC doesn't mean that the compiler

-
-    Correct. However, a non-trivial shared library typically won't be
-    position-independent unless explicitly compiled with
-    -fPIC. Linux/glibc indeed does not require a shared library to be
-    position-independent; instead, it will perform the relocations in the
-    binary, even if they refer to code pages. As a result, those relocated
-    pages won't be shared across processes, anymore.

-USING PHP 3 AND PHP 4 AS CONCURRENT APACHE MODULES
-
-   Recent operating systems provide the ability to perform versioning and
-   scoping. This features make it possible to let PHP 3 and PHP 4 run as
-   concurrent modules in one Apache server. 
-   
-   This feature is known to work on the following platforms:
-
-   - Linux with recent binutils (binutils 2.9.1.0.25 tested)
-   - Solaris 2.5 or better
-   - FreeBSD (3.2, 4.0 tested)
-   - IRIX64 6.5
-   
-   To enable it, configure PHP 3 and PHP 4 to use APXS (--with-apxs) and the
-   necessary link extensions (--enable-versioning). Otherwise, all standard
-   installations instructions apply. For example:
-
-   		$ ./configure \
-				--with-apxs=/apache/bin/apxs \
-				--enable-versioning \
-				--with-mysql \
-				--enable-track-vars
-
-   If this also works on your platform or if you know a way to do it, please
-   report it to our bug database at http://bugs.php.net

-This is the first file you should be reading after you get your CVS account.
-We'll assume you're basically familiar with CVS, but feel free to post
-your questions on the mailing list.
-
-PHP is developed through the efforts of a large number of people.
-Collaboration is a Good Thing(tm), and CVS lets us do this. Thus, following
-some basic rules with regards to CVS usage will:
-
-   a. Make everybody happier, especially those responsible for maintaining
-      the CVS itself.
-   b. Keep the changes consistently well documented and easily trackable.
-   c. Prevent some of those 'Oops' moments.
-   d. Increase the general level of good will on planet Earth.
-
-
-Having said that, here are the organizational rules:
-
-   1. Respect other people working on the project.
-
-   2. Discuss any significant changes on the list before committing. 
-
-   3. Look at EXTENSIONS file to see who is the primary maintainer of
-      the code you want to contribute to.
-
-   4. If you "strongly disagree" about something another person did, don't
-      start fighting publicly - take it up in private email.
-
-   5. If you don't know how to do something, ask first!
-
-   6. Test your changes before committing them. We mean it. Really.
-	
-
-The next few rules are more of a technical nature.
-
-   1. DO NOT TOUCH ChangeLog! It is automagically updated from the commit
-      messages every day. Woe be to those who attempt to mess with it.
-
-   2. All news updates intended for public viewing, such as new features,
-      bug fixes, improvements, etc., should go into the NEWS file. Also see
-      the note below about automatically updating NEWS in your commit message.
-
-   3. Do not commit multiple file and dump all messages in one commit. If you
-      modified several unrelated files, commit each group separately and
-      provide a nice commit message for each one. See example below.
-
-   4. Do write your commit message in such a way that it makes sense even
-      without the corresponding diff. One should be able to look at it, and
-      immediately know what was modified. Definitely include the function name
-      in the message as shown below.
-
-   5. In your commit messages, keep each line shorter than 80 characters. And
-      try to align your lines vertically, if they wrap. It looks bad otherwise.
-
-   6. If you modified a function that is callable from PHP, prepend PHP to
-      the function name as shown below.
-
-
-The format of the commit messages is pretty simple.
-
-If a line begins with #, it is taken to be a comment and will not appear
-in the ChangeLog.  If the line begins with @, it will be redirected to the
-NEWS file. Everything else goes into the ChangeLog.
-
-It is important to note that if your comment or news logline spans multiple
-lines, you have to put # or @ at the beginning of _every_ such line. Every 
-entry in NEWS has to have a name after it, so if you did it with someone's 
-help, put both your names there. Your name WILL NOT be automatically put
-at the end of the NEWS entry - so, please provide it yourself.
-
-Example. Say you modified two files, datetime.c and string.c. In datetime.c
-you added a new format option for date() function, and in string.c you fixed
-a memory leak in php_trim(). Don't commit both of these at once. Commit them
-separately and try to make sure your commit messages look something like the
-following.
-
-For datetime.c:
-
-(PHP date) Added new 'K' format modifier for printing out number of
-           days until New Year's Eve.
-@- Added new 'K' format modifier that will output the number of days
-@  until New Year's Eve. (Bob)
-
-For string.c:
-(php_trim) Fixed a memory leak resulting from improper use of zval_dtor().
-# Man, that thing was leaking all over the place!
-@- Memory leak in trim() function has finally been fixed. (Bob)
-
-The lines above marked with @ will go into NEWS file automagically, and the
-# lines will be omitted from the ChangeLog. Alternatively, you might want
-to modify NEWS file directly and not use the @ lines.
-
-If you don't see your messages in ChangeLog and NEWS right away, don't worry!
-These files are updated once a day, so your stuff will not show up until
-somewhat later. Don't go adding stuff to NEWS by hand if you already put @
-lines in the commit message.
-
-You can use LXR (http://lxr.php.net/) and Bonsai (http://bonsai.php.net/)
-to look at PHP CVS repository in various ways.
-
-To receive daily updates to ChangeLog and NEWS, send an empty message to
-php-cvs-daily-subscribe@lists.php.net.

-WHAT IT IS
-
-  It's a tool for automatically creating the basic framework for a PHP module
-  and writing C code handling arguments passed to your functions from a simple
-  configuration file. See an example at the end of this file.
-
-HOW TO USE IT
-
-  Very simple. First, cd do directory ext/ in PHP 4 sources. If you just need
-  the basic framework and will be writing all the code in your functions
-  yourself, you can now do
-
-   ./ext_skel --extname=module_name
-
-  and everything you need is placed in directory module_name. In fact, if you
-  don't need to test the existence of any external header files, libraries or
-  functions in them, the module is already almost ready to be compiled in PHP.
-  Just remove 3 comments in your_module_name/config.m4, cd back up to PHP
-  sources top directory, and do
-
-    ./buildconf; ./configure --enable-module_name; make
-
-  But if you already have planned the overall scheme of your module, what
-  functions it will contain, their return types and the arguments they take
-  (a very good idea) and don't want to bother yourself with creating function
-  definitions and handling arguments passed yourself, it's time to create a
-  function definitions file, which you will give as an argument to ext_skel
-  with option
-
-    --proto=filename.
-
-FORMAT OF FUNCTION DEFINITIONS FILE
-
-  All the definitions must be on one line. In it's simplest form, it's just
-  the function name, ie.
-
-    my_function
-
-  but then you'll be left with an almost empty function body without any
-  argument handling.
-
-  Arguments are given in parenthesis after the function name, and are of
-  the form 'argument_type argument_name'. Arguments are separated from each
-  other with a comma and optional space. Argument_type can be one of int,
-  bool, double, float, string, array, object or mixed.
-
-  An optional argument is separated from the previous by an optional space,
-  then '[' and of course comma and optional space, like all the other
-  arguments. You should close a row of optional arguments with same amount of
-  ']'s as there where '['s. Currently, it does not harm if you forget to do it
-  or there is a wrong amount of ']'s, but this may change in the future.
-
-	An additional short description may be added after the parameters. 
-  If present it will be filled into the 'proto' header comments in the stubs
-  code and the <refpurpose> tag in the XML documentation.
-
-  An example:
-
-    my_function(int arg1, int arg2 [, int arg3 [, int arg4]]) this is my 1st
-
-  Arguments arg3 and arg4 are optional.
-
-  If possible, the function definition should also contain it's return type
-  in front of the definition. It's not actually used for any C code generating
-  purposes but PHP in-source documentation instead, and as such, very useful.
-  It can be any of int, double, string, bool, array, object, resource, mixed
-  or void.
-
-  The file must contain nothing else but function definitions, no comments or
-  empty lines.
-
-OTHER OPTIONS
-
-    --no-help
-
-  By default, ext_skel creates both comments in the source code and a test
-  function to help first time module writers to get started and testing
-  configuring and compiling their module. This option turns off all such things
-  which may just annoy experienced PHP module coders. Especially useful with
-
-    --stubs=file
-
-  which will leave out also all module specific stuff and write just function
-  stubs with function value declarations and passed argument handling, and
-  function entries and definitions at the end of the file, for copying and
-  pasting into an already existing module.
-
-    --assign-params
-    --string-lens
-
-  By default, function proto 'void foo(string bar)' creates the following:
-     ...
-     zval **bar;
-     ... (zend_get_parameters_ex() called in the middle...)
-     convert_to_string_ex(bar);
-
-  Specifying both of these options changes the generated code to:
-     ...
-     zval **bar_arg;
-     int bar_len;
-     char *bar = NULL;
-     ... (zend_get_parameters_ex() called in the middle...)
-     convert_to_string_ex(bar_arg);
-     bar = Z_STRVAL_PP(bar_arg);
-     bar_len = Z_STRLEN_PP(bar_arg);
-
-  You shouldn't have to ask what happens if you leave --string-lens out. If you
-  have to, it's questionable whether you should be reading this document.
-
-    --with-xml[=file]
-
-  Creates the basics for phpdoc .xml file.
-
-    --full-xml
-
-  Not implemented yet. When or if there will ever be created a framework for
-  self-contained extensions to use phpdoc system for their documentation, this
-  option enables it on the created xml file.
-
-CURRENT LIMITATIONS, BUGS AND OTHER ODDITIES
-
-  Only arguments of types int, bool, double, float, string and array are
-  handled. For other types you must write the code yourself. And for type
-  mixed, it wouldn't even be possible to write anything, because only you
-  know what to expect.
-  
-  It can't handle correctly, and probably never will, variable list of
-  of arguments. (void foo(int bar [, ...])
-
-  Don't trust the generated code too much. It tries to be useful in most of
-  the situations you might encounter, but automatic code generation will never
-  beat a programmer who knows the real situation at hand. ext_skel is generally
-  best suited for quickly generating a wrapper for c-library functions you
-  might want to have available in PHP too.
-
-  This program doesn't have a --help option. It has --no-help instead.
-
-EXAMPLE
-
-  The following _one_ line
-
-  bool my_drawtext(resource image, string text, resource font, int x, int y [, int color])
-
-  will create this function definition for you (note that there are a few
-  question marks to be replaced by you, and you must of course add your own
-  value definitions too):
-
-/* {{{ proto bool my_drawtext(resource image, string text, resource font, int x, int y[, int color])
-    */
-PHP_FUNCTION(my_drawtext)
-{
-	zval **image, **text, **font, **x, **y, **color;

-New parameter parsing functions
-===============================
-
-It should be easier to parse input parameters to an extension function.
-Hence, borrowing from Python's example, there are now a set of functions
-that given the string of type specifiers, can parse the input parameters
-and store the results in the user specified variables. This avoids most
-of the IS_* checks and convert_to_* conversions. The functions also
-check for the appropriate number of parameters, and try to output
-meaningful error messages.
-
-
-Prototypes
----------
-/* Implemented. */
-int zend_parse_parameters(int num_args TSRMLS_DC, char *type_spec, ...);
-int zend_parse_parameters_ex(int flags, int num_args TSRMLS_DC, char *type_spec, ...);
-
-The zend_parse_parameters() function takes the number of parameters
-passed to the extension function, the type specifier string, and the
-list of pointers to variables to store the results in. The _ex() version
-also takes 'flags' argument -- current only ZEND_PARSE_PARAMS_QUIET can
-be used as 'flags' to specify that the function should operate quietly
-and not output any error messages.
-
-Both functions return SUCCESS or FAILURE depending on the result.
-
-The auto-conversions are performed as necessary. Arrays, objects, and
-resources cannot be autoconverted.
-
-
-Type specifiers
---------------
- l	- long
- d	- double
- s	- string (with possible null bytes) and its length
- b	- boolean, stored in zend_bool
- r	- resource (stored in zval)
- a	- array
- o	- object (of any type)
- O	- object (of specific type, specified by class entry)
- z	- the actual zval
-
- The following characters also have a meaning in the specifier string:
-     | - indicates that the remaining parameters are optional, they
-		 should be initialized to default values by the extension since they
-		 will not be touched by the parsing function if they are not
-		 passed to it.
-	 / - use SEPARATE_ZVAL_IF_NOT_REF() on the parameter it follows
-	 ! - the parameter it follows can be of specified type or NULL (only applies
-	     to 'a', 'o', 'O', 'r', and 'z'). If NULL is passed, the results
-		 pointer is set to NULL as well.
-
-Examples
--------

-QNX4 Installation Notes
-----------------------
-
-NOTE: General installation instructions are in the INSTALL file 
-
-
-1. To compile and test PHP3 you have to grab, compile and install:
-	- GNU dbm library or another db library;
-	- GNU bison (1.25 or later; 1.25 tested);
-	- GNU flex (any version supporting -o and -P options; 2.5.4 tested);
-	- GNU diffutils (any version supporting -w option; 2.7 tested);
-
-2. To use CVS version you may need also:
-	- GNU CVS (1.9 tested);
-	- GNU autoconf (2.12 tested);
-	- GNU m4 (1.3 or later preferable; 1.4 tested);
-
-3. To run configure define -lunix in command line:
-	LDFLAGS=-lunix ./configure
-
-4. To use Sybase SQL Anywhere define ODBC_QNX and CUSTOM_ODBC_LIBS in
-	command line and run configure with --with-custom-odbc:
-	CFLAGS=-DODBC_QNX LDFLAGS=-lunix CUSTOM_ODBC_LIBS="-ldblib -lodbc" ./configure --with-custom-odbc=/usr/lib/sqlany50
-   If you have SQL Anywhere version 5.5.00, then you have to add 
-	CFLAGS=-DSQLANY_BUG
-   to workaround its SQLFreeEnv() bug. Other versions has not been tested,
-   so try without this flag first.
-
-5. To build the Apache module, you may have to hardcode an include path for 
-   alloc.h in your Apache base directory:
-	- APACHE_DIRECTORY/src/httpd.h: 
-		change	#include "alloc.h"
-		to 		#include "APACHE_DIRECTORY/src/alloc.h"
-   Unless you want to use system regex library, you have to hardcode also
-   a path to regex.h:
-	- APACHE_DIRECTORY/src/conf.h:  
-		change  #include <regex.h>
-		to		#include "APACHE_DIRECTORY/src/regex/regex.h"
-   I don't know so far why this required for QNX, may be it is Watcom 
-   compiler problem.
-
-  If you building Apache module with SQL Anywhere support, you'll get
-  symbol conflict with BOOL. It is defined in Apache (httpd.h) and in 
-  SQL Anywhere (odbc.h). This has nothing to do with PHP, so you have to 
-  fix it yourself someway.
-
-6. With above precautions, it should compile as is and pass regression
-	tests completely:
-		make
-		make check
-		make install
-
-	Don't bother me unless you really sure you made	that all but it 
-	still doesn't work.

-HOW TO CREATE A SELF-CONTAINED PHP EXTENSION
-
-  A self-contained extension can be distributed independently of
-  the PHP source. To create such an extension, three things are
-  required:
-
-  - Makefile template (Makefile.in)
-  - Configuration file (config.m4)
-  - Source code for your module
-
-  We will describe now how to create these and how to put things
-  together.
-
-PREPARING YOUR SYSTEM
-
-  While the result will run on any system, a developer's setup needs these
-  tools:
-
-    GNU autoconf
-    GNU automake
-    GNU libtool
-    GNU m4
-
-  All of these are available from 
-
-    ftp://ftp.gnu.org/pub/gnu/
-
-CONVERTING AN EXISTING EXTENSION
-
-  Just to show you how easy it is to create a self-contained
-  extension, we will convert an embedded extension into a
-  self-contained one. Install PHP and execute the following
-  commands.
-  
-     $ mkdir /tmp/newext
-     $ cd /tmp/newext
-
-  You now have an empty directory. We will copy the files from
-  the mysql extension:
-
-     $ cp -rp php-4.0.X/ext/mysql/* .
-
-  It is time to finish the module. Run:
-
-     $ phpize
-
-  You can now ship the contents of the directory - the extension
-  can live completely on its own.
-
-  The user instructions boil down to
-
-     $ ./configure \
-            [--with-php-config=/path/to/php-config] \
-            [--with-mysql=MYSQL-DIR]
-     $ make install
-
-  The MySQL module will either use the embedded MySQL client 
-  library or the MySQL installation in MYSQL-DIR.
-
-
-DEFINING THE NEW EXTENSION
-
-  Our demo extension is called "foobar".
-
-  It consists of two source files "foo.c" and "bar.c"
-  (and any arbitrary amount of header files, but that is not
-  important here).
-  
-  The demo extension does not reference any external 
-  libraries (that is important, because the user does not
-  need to specify anything).
-
-
-CREATING THE MAKEFILE TEMPLATE 
-  
-  The Makefile Template (Makefile.in) contains three lines:
-
------------------------------------------------------------------------------
-LTLIBRARY_SHARED_NAME = foobar.la
-LTLIBRARY_SOURCES     = foo.c bar.c
-
-include $(top_srcdir)/build/dynlib.mk
------------------------------------------------------------------------------
-
-  LTLIBRARY_SHARED_NAME specifies the name of the extension.
-  It must be of the form `ext-name.la'.
-
-  LTLIBRARY_SOURCES specifies the names of the sources files. You can
-  name an arbitrary number of source files here.
-
-  The final include directive includes the build rules (you usually
-  don't need to care about what happens there). rules.mk and other
-  files are installed by phpize which we will cover later.
-
-
-CREATING THE M4 CONFIGURATION FILE
-
-  The m4 configuration can perform additional checks. For a 
-  self-contained extension, you do not need more than a few
-  macro calls.
-
------------------------------------------------------------------------------
-PHP_ARG_ENABLE(foobar,whether to enable foobar,
-[  --enable-foobar            Enable foobar])
-
-if test "$PHP_FOOBAR" != "no"; then
-  PHP_EXTENSION(foobar, $ext_shared)
-fi
------------------------------------------------------------------------------
-
-  PHP_ARG_ENABLE will automatically set the correct variables, so
-  that the extension will be enabled by PHP_EXTENSION in shared mode.
-
-  Please use always PHP_ARG_ENABLE or PHP_ARG_WITH. Even if you do not
-  plan to distribute your module with PHP, these facilities allow you
-  to integrate your module easily into the main PHP module framework.
-
-CREATING SOURCE FILES
-
-  ext_skel can be of great help when creating the common code for all modules
-  in PHP for you and also writing basic function definitions and C code for
-  handling arguments passed to your functions. See README.EXT_SKEL for further
-  information.
-
-  As for the rest, you are currently alone here. There are a lot of existing
-  modules, use a simple module as a starting point and add your own code.
-
-
-CREATING THE SELF-CONTAINED EXTENSION
-
-  Put Makefile.in, config.m4 and the source files into one directory.
-  Then run phpize (this is installed during make install by PHP 4.0).
-  For example, if you configured PHP with --prefix=/php, you would run
-
-     $ /php/bin/phpize
-
-  This will automatically copy the necessary build files and create
-  configure from your config.m4.
-
-  And that's it. You now have a self-contained extension.
-
-INSTALLING A SELF-CONTAINED EXTENSION
-
-  An extension can be installed by running:
-
-     $ ./configure \
-            [--with-php-config=/path/to/php-config]
-     $ make install
-
-ADDING SHARED MODULE SUPPORT TO A MODULE
-
-  In order to be useful, a self-contained extension must be loadable
-  as a shared module. I will explain now how you can add shared module 
-  support to an existing module called foo.
-
-  1. In config.m4, use PHP_ARG_WITH/PHP_ARG_ENABLE. Then you will
-     automatically be able to use --with-foo=shared or
-     --enable-foo=shared.
-
-  2. In config.m4, use PHP_EXTENSION(foo, $ext_shared) to enable
-     building the extension.
-
-  3. Add the following line to Makefile.in:
-
-        LTLIBRARY_SHARED_NAME = foo.la
-
-  4. Add the following lines to your C source file:
-
-        #ifdef COMPILE_DL_FOO
-        ZEND_GET_MODULE(foo)
-        #endif

-An Overview of the PHP Streams abstraction
-==========================================
-$Id$
-
-Please send comments to: Wez Furlong <wez@thebrainroom.com>
-
-Note: this doc is preliminary and is intended to give the reader an idea of
-how streams work and should be used.
-
-Why Streams?
-============
-You may have noticed a shed-load of issock parameters flying around the PHP
-code; we don't want them - they are ugly and cumbersome and force you to
-special case sockets and files everytime you need to work with a "user-level"
-PHP file pointer.
-Streams take care of that and present the PHP extension coder with an ANSI
-stdio-alike API that looks much nicer and can be extended to support non file
-based data sources.
-
-Using Streams
-=============
-Streams use a php_stream* parameter just as ANSI stdio (fread etc.) use a
-FILE* parameter.
-
-The main functions are:
-
-PHPAPI size_t php_stream_read(php_stream * stream, char * buf, size_t count);
-PHPAPI size_t php_stream_write(php_stream * stream, const char * buf, size_t
-	  	count);
-PHPAPI int php_stream_eof(php_stream * stream);
-PHPAPI int php_stream_getc(php_stream * stream);
-PHPAPI char *php_stream_gets(php_stream * stream, char *buf, size_t maxlen);
-PHPAPI int php_stream_close(php_stream * stream);
-PHPAPI int php_stream_flush(php_stream * stream);
-PHPAPI int php_stream_seek(php_stream * stream, off_t offset, int whence);
-PHPAPI off_t php_stream_tell(php_stream * stream);
-
-These (should) behave in the same way as the ANSI stdio functions with similar
-names: fread, fwrite, feof, fgetc, fgets, fclose, fflush, fseek, ftell.
-
-Opening Streams
-===============
-Ultimately, I aim to implement an fopen_wrapper-like call to do this with
-minimum fuss.
-Currently, mostly for testing purposes, you can use php_stream_fopen to open a
-stream on a regular file.
-
-PHPAPI php_stream * php_stream_fopen(const char * filename, const char *
-		mode);
-
-This call behaves just like fopen(), except it returns a stream instead of a
-FILE *
-
-Casting Streams
-===============
-What if your extension needs to access the FILE* of a user level file pointer?
-You need to "cast" the stream into a FILE*, and this is how you do it:
-
-FILE * fp;
-php_stream * stream; /* already opened */
-
-if (php_stream_cast(stream, PHP_STREAM_AS_STDIO, &fp, 1) == FAILURE)	{
-	RETURN_FALSE;
-}
-
-The prototype is:
-
-PHPAPI int php_stream_cast(php_stream * stream, int castas, void ** ret, int
-		show_err);
-
-The show_err parameter, if non-zero, will cause the function to display an
-appropriate error message of type E_WARNING if the cast fails.
-
-castas can be one of the following values:
-PHP_STREAM_AS_STDIO - a stdio FILE*
-PHP_STREAM_AS_FD - a generic file descriptor
-PHP_STREAM_AS_SOCKETD - a socket descriptor
-
-If you ask a socket stream for a FILE*, the abstraction will use fdopen to
-create it for you.  Be warned that doing so may cause buffered data to be lost
-if you mix ANSI stdio calls on the FILE* with php stream calls on the stream.
-
-If your system has the fopencookie function, php streams can synthesize a
-FILE* on top of any stream, which is useful for SSL sockets, memory based
-streams, data base streams etc. etc.
-NOTE: There might be situations where this is not desireable, and we need to
-provide a flag to inform the casting routine of this.
-
-You can use:
-
-PHPAPI int php_stream_can_cast(php_stream * stream, int castas)
-
-to find out if a stream can be cast, without actually performing the cast, so
-to check if a stream is a socket you might use:
-
-if (php_stream_can_cast(stream, PHP_STREAM_AS_SOCKETD) == SUCCESS)	{
-	/* it's a socket */
-}
-
-
-Stream Internals
-================
-
-There are two main structures associated with a stream - the php_stream
-itself, which holds some state information (and possibly a buffer) and a
-php_stream_ops structure, which holds the "virtual method table" for the
-underlying implementation.
-
-The php_streams ops struct consists of pointers to methods that implement
-read, write, close, flush, seek, gets and cast operations.  Of these, an
-implementation need only implement write, read, close and flush.  The gets
-method is intended to be used for non-buffered streams if there is an
-underlying method that can efficiently behave as fgets.  The ops struct also
-contains a label for the implementation that will be used when printing error
-messages - the stdio implementation has a label of "STDIO" for example.
-
-The idea is that a stream implementation defines a php_stream_ops struct, and
-associates it with a php_stream using php_stream_alloc.
-
-As an example, the php_stream_fopen() function looks like this:
-
-PHPAPI php_stream * php_stream_fopen(const char * filename, const char * mode)
-{
-	FILE * fp = fopen(filename, mode);
-	php_stream * ret;
-	
-	if (fp)	{
-		ret = php_stream_alloc(&php_stream_stdio_ops, fp, 0, 0, mode);
-		if (ret)
-			return ret;
-
-		fclose(fp);
-	}
-	return NULL;
-}
-
-php_stream_stdio_ops is a php_stream_ops structure that can be used to handle
-FILE* based streams.
-
-A socket based stream would use code similar to that above to create a stream
-to be passed back to fopen_wrapper (or it's yet to be implemented successor).
-
-The prototype for php_stream_alloc is this:
-
-PHPAPI php_stream * php_stream_alloc(php_stream_ops * ops, void * abstract,
-		size_t bufsize, int persistent, const char * mode)
-
-ops is a pointer to the implementation,
-abstract holds implementation specific data that is relevant to this instance
-of the stream,
-bufsize is the size of the buffer to use - if 0, then buffering at the stream
-level will be disabled (recommended for underlying sources that implement
-their own buffering - such a FILE*),
-persistent controls how the memory is to be allocated - persistently so that
-it lasts across requests, or non-persistently so that it is freed at the end
-of a request (it uses pemalloc),
-mode is the stdio-like mode of operation - php streams places no real meaning
-in the mode parameter, except that it checks for a 'w' in the string when
-attempting to write (this may change).
-
-The mode parameter is passed on to fdopen/fopencookie when the stream is cast
-into a FILE*, so it should be compatible with the mode parameter of fopen().
-
-Writing your own stream implementation
-======================================
-
-First, you need to figure out what data you need to associate with the
-php_stream.  For example, you might need a pointer to some memory for memory
-based streams, or if you were making a stream to read data from an RDBMS like
-mysql, you might want to store the connection and rowset handles.
-
-The stream has a field called abstract that you can use to hold this data.
-If you need to store more than a single field of data, define a structure to
-hold it, allocate it (use pemalloc with the persistent flag set
-appropriately), and use the abstract pointer to refer to it.
-
-For structured state you might have this:
-
-struct my_state	{
-	MYSQL conn;
-	MYSQL_RES * result;
-};
-
-struct my_state * state = pemalloc(sizeof(struct my_state), persistent);
-
-/* initialize the connection, and run a query, using the fields in state to
- * hold the results */
-
-state->result = mysql_use_result(&state->conn);
-
-/* now allocate the stream itself */
-stream = php_stream_alloc(&my_ops, state, 0, persistent, "r");
-
-/* now stream->abstract == state */
-
-Once you have that part figured out, you can write your implementation and
-define the your own php_stream_ops struct (we called it my_ops in the above
-example).
-
-For example, for reading from this wierd mysql stream:
-
-static size_t php_mysqlop_read(php_stream * stream, char * buf, size_t count)
-{
-	struct my_state * state = (struct my_state*)stream->abstract;
-
-	if (buf == NULL && count == 0)	{
-		/* in this special case, php_streams is asking if we have reached the
-		 * end of file */
-		if (... at end of file ...)
-			return EOF;
-		else
-			return 0;
-	}
-	
-	/* pull out some data from the stream and put it in buf */
-	... mysql_fetch_row(state->result) ...
-	/* we could do something strange, like format the data as XML here,
-		and place that in the buf, but that brings in some complexities,
-		such as coping with a buffer size too small to hold the data,
-		so I won't even go in to how to do that here */
-}
-
-Implement the other operations - remember that write, read, close and flush
-are all mandatory.  The rest are optional.  Declare your stream ops struct:
-
-php_stream_ops my_ops = {
-	php_mysqlop_write, php_mysqlop_read, php_mysqlop_close,
-	php_mysqlop_flush, NULL, NULL, NULL,
-	"Strange mySQL example"
-}
-
-Thats it!
-
-Take a look at the STDIO implementation in streams.c for more information
-about how these operations work.
-The main thing to remember is that in your close operation you need to release
-and free the resources you allocated for the abstract field.  In the case of
-the example above, you need to use mysql_free_result on the rowset, close the
-connection and then use pefree to dispose of the struct you allocated.
-You may read the stream->persistent field to determine if your struct was
-allocated in persistent mode or not.

-Using PHP4 with the Zeus Web Server
-----------------------------------
-
-Zeus fully supports running PHP in combination with our
-webserver. There are three different interfaces that can be used to
-enable PHP:
-
-* CGI
-* ISAPI
-* FastCGI
-
-Of the three, we recommend using FastCGI, which has been tested and
-benchmarked as providing the best performance and reliability.
-
-Full details of how to install PHP are available from our
-website, at:
-
-http://support.zeus.com/products/php.html
-
-If you have any problems, please check the support site for more
-up-to-date information and advice.
-
-
-Quick guide to installing FastCGI with Zeus
-------------------------------------------
-
-Step 1 - obtain and install FastCGI development kit.
-
-Grab the package from:
-http://www.fastcgi.com/dist/devkit_2.2.0.tar.gz
-
-Extract the package and follow the instructions:
-        ./configure
-        make
-        make export
-(run the last as root)
-
-This will install to /usr/local/lib/libfcgi.a
-                and  /usr/local/include/*fcgi*
-
-
-
-Step 2 - Compile PHP as FastCGI.
-
-Compile as follows:
-        ./configure --with-fastcgi
-        make
-
-Note that PHP has many options to the configure script -
-e.g. --with-mysql. You will probably want to select your usual options
-before compiling; the above is just a bare minimum, for illustration.
-
-After compilation finishes, you will be left with an executable
-program called 'php'. Copy this into your document root, under a
-dedicated FastCGI directory (e.g. $DOCROOT/fcgi-bin/php)
-
-
-Step 3 - configure Zeus
-
-Four stages:
-        -  enable FastCGI
-        -  configure FastCGI
-        -  setup alias for FastCGI
-        -  setup alias for PHP
-
-1) Using the admin server, go to the 'module configuration' page for
-your virtual server, and ensure that 'fastcgi' is enabled (select the
-tickbox to the left).
-
-2) While we can run FastCGI's locally, there are known problems with
-some OS's (specifically, the communication between web server and
-FastCGI happens over a unix domain socket, and some OS's have trouble
-sustaining high connection rates over these sockets). So instead, we
-are going to set up the PHP FastCGI to run 'remotely' over localhost
-(this uses TCP sockets, which do not suffer this problem). Go to the
-'fastcgi configuration' page, and under 'add remote fastcgi':
-        Add Remote FastCGI
-                Docroot path            /fcgi-bin/php
-                Remote machine          localhost:8002
-The first entry is where you saved PHP, above.
-The second entry is localhost:<any unused port>
-We will start the FastCGI listening on this port shortly.
-Click 'update' to commit these changes.
-
-3) Go to the path mapping module and add an alias for FastCGI:
-        Add Alias
-                Docroot path            /fcgi-bin
-                Filesystem directory    /path/to/docroot/fcgi-bin
-                Alias type              fastcgi
-Click 'update' to commit these changes
-
-4) Also on the path mapping module, add a handler for PHP:
-        Add handler
-                File extension          php
-                Handler                 /fcgi-bin/php
-Click 'update' to commit these changes
-
-Finally restart your virtual server for these changes to take effect.
-
-
-Step 4 - start PHP as a FastCGI runner
-
-When you start PHP, it will pre-fork a given number of child processes
-to handle incoming PHP requests. Each process will handle a given
-number of requests before exiting (and being replaced by a newly
-forked process). You can control these two parameters by setting the
-following environment variables BEFORE starting the FastCGI runner:
-
-PHP_FCGI_CHILDREN - the number of child processes to pre-fork. If not
-set, defaults to 8.
-
-PHP_FCGI_MAX_REQUESTS - the number of requests each PHP child process
-handles before exiting. If not set, defaults to 500.
-
-To start the FastCGI runner, execute '$ZEUSHOME/web/bin/fcgirunner
-8002 $DOCROOT/fcgi-bin/php'.  Substitute the appropriate values for
-$ZEUSHOME and $DOCROOT; also substitute for 8002 the port you chose,
-above.
-
-To stop the runner (e.g. to experiment with the above environment
-variables) you will need to manually stop and running PHP
-processes. (Use 'ps' and 'kill'). As it is PHP which is forking lots
-of children and not the runner, Zeus unfortunately cannot keep track
-of what processes are running, sorry. A typical command line may look
-like 'ps -efl | grep $DOCROOT/fcgi-bin/php | grep -v grep | awk
-'{print $4}' | xargs kill'

-  6  Summary
-
-
-1. Introduction
-
-   This cycle should take place over roughly 10 days.  When it is
-   decided it is time for an Release to occur Andi/Zeev (Or 
-   Whoever) will tarball RC1, Tag & Branch CVS (see section 4)
-   and then announce the RC on PHP-QA and PHP-DEV.  At this 
-   point the build tracker and QA Bug System come into play.
-   If you successfully build PHP then report it in the build
-   tracker, If you then run and complete all the tests you
-   should report this too in the build tracker when
-   these features become avalible.
-
-2. Dealing with Bugs
-
-2.1 As a QA Team member
-
-   If you find a bug in an RC that you think is a showstopper
-   then, even if it is a known bug, you should report it in the
-   QA Bug system.  This marks the bug for discussion at least,
-   and preferably fixing before the actual release.  This system
-   is separate from the main bugs system so that important bugs
-   dont get lost in the midst if lots of feature/change request
-   in the approach to a release.  It is imperitive where 
-   appropraite that as a QA'er a test script, Configure options
-   and PHP.ini files are provided to enable the developer to
-   reproduce the bug, this is an important part of our job.  If
-   you have a serious bug then you should also create a test
-   script to be added to the tests dir of the php source so
-   that at the end of the process to enable us to make sure bug
-   does not return.  It is not difficult to create these test
-   scripts and a readme on it can be found in
-   php4/tests/README.
-
-
-2.2 As a Developer
-
-   What should happen is that when a bug is reported it
-   is send to php-dev and php-qa as with other bugs.  We should
-   have far stricter assignment system in this bug cycle rather
-   than just leaving them. Once again bugs should be able to be
-   marked as To Be Fixed Before release or moved to other bug
-   system. (This is currently the Release Masters responsibility)
-
-   Then before the actual release the qa bugs system can be
-   checked and if there are outstanding To Be Fixed Before
-   release bugs the Developers can see this easyly rather than
-   show stoppers being dismissed and not worried about.
-
-   When a bug is fixed the QAer who reported the bug is emailed
-   and asked to test again and see if the bug is fixed.
-
-3 Releasing another RC
-
-   If it is felt necessary that a 2nd RC is needed then it
-   should be packaged as before and announced to both lists
-   again. The testing process then starts again, the RC2 is 
-   added to the build tracker and QA'ers are asked to build and
-   retest the scripts as appropriate, espectially if you
-   reported a bug, you should test thourghly for your 
-   bug and make sure it no longer occurs. This will normally
-   add anouther 3 days to the cycle, giving QA'ers time to
-   build test and report back, then for developers to 
-   fix any problems.
-
-4 CVS during the release process
-
-   At the point where the first RC is create a branch is
-   formed. This branch is not altered form that point onward
-   other than major bug fixes. Minor non important bug 
-   fixes should not be applied to this branch but to the main
-   tree instead. Any major bug fixes should be applied to both
-   trees. The developer should test and check the RC tree then
-   also test and check the MAIN tree. This is their
-   responsibility to make sure (as far as possible) that the
-   bug fix works on both trees.
-
-4.1 Useful CVS Commands
-
-   To create a Branch <Should only be done by person tarballing
-   the RC (The Release Master)>:
-
-	$ cvs tag -b php_4_0_<Version>RC<NUMBER> 
-   IE:
-	$ cvs tag -b php_4_0_1RC1
-
-   This should be executed in the PHP directory of an up to
-   date checkout. Remember to also tag the Zend and TSRM repositories.
-
-   You can retrieve a branch in one of two ways: by checking it
-   out fresh from the repository, or by switching an existing
-   working copy over to the branch, I would suggest you
-   checkout a new copy.
-
-   To check out a new copy:
-	$ cvs checkout -r php_4_0_<Version>RC<NUMBER> php4
-   IE:
-	$ cvs checkout -r php_4_0_1RC1 php4
-
-
-   To switch a working copy (Not recomended due to possible
-   commiting to wrong branch)
-	$ cvs update -r php_4_0_<Version>RC<NUMBER> php4
-   IE:
-	$ cvs update -r php_4_0_1RC1 php4
-
-   This should be done in the PHP4 directory itself.
-
-   To revert back to normal branch you should use the
-   following:
-	$ cvs update -A
-
-   To Commit to the branch you follow exactly the same
-   procedure as normal
-	$ cvs commit file.c
-
-   MAKE SURE YOU DO NOT COMMIT TO THE WRONG BRANCH.
-
-5 The Final Release
-
-   When it is time to make the final release the following
-   proceedure should be followed. The person who is tarballing
-   the final release should check the QA bugs system and make
-   sure there are no showstoppers left unfixed. If there are
-   then bug the person the bug is assigned to until they fix
-   it. If there are no more qa bugs then they should tag the
-   branch as  php_4_0_<Version> and tarball as usual. An email
-   should be sent to PHP-GEN, PHP_DEV and PHP-QA about the new
-   release and it should be added to php.net. The windows
-   binaries and servelets should be built as soon as possible
-   and added too, as should the windows installer.
-
-6 Summary
-
-   Here is a summary of what a release cycle might look like:
-
-   Thurs: RC is agreed on and packaged, an email is sent to   
-          PHP_QA and PHP-DEV, the CVS is Branched and the

-This file is by no means thorough documentation of the PHP API,
-and is intended for developers who are familiar with the PHP 3.0 API,
-and want to port their code to PHP 4.0, or take advantage of its new
-features.  For highlights about the PHP 3.0 API, consult apidoc.txt.
-
-Zeev
-
--------------------------------------------------------------------------
-
-I'm going to try to list the important changes in API and programming
-techniques that are involved in developing modules for PHP4/Zend, as
-opposed to PHP3.  Listing the whole PHP4 API is way beyond my scope here,
-it's mostly a 'diff' from the apidoc.txt, which you're all pretty familiar
-with.
-An important note that I neglected to mention yesterday - the php4 tree is
-based on the php 3.0.5 tree, plus all 3.0.6 patches hand-patched into it.
-Notably, it does NOT include any 3.0.7 patches.  All of those have to be
-reapplied, with extreme care - modules should be safe to patch (mostly),
-but anything that touches the core or main.c will almost definitely require
-changes in order to work properly.
-
-[1]  Symbol Tables
-
-One of the major changes in Zend involves changing the way symbols tables
-work.  Zend enforces reference counting on all values and resources.  This
-required changes in the semantics of the hash tables that implement symbol
-tables.  Instead of storing pval in the hashes, we now store pval *.  All
-of the API functions in Zend were changed in a way that this change is
-completely transparent.  However, if you've used 'low level' hash functions
-to access or update elements in symbol tables, your code will require
-changes.  Following are two simple examples, one demonstrates the
-difference between PHP3 and Zend when reading a symbol's value, and the
-other demonstrates the difference when writing a value.
-
-php3_read()
-{
-	pval *foo;
-
-	_php3_hash_find(ht, "foo", sizeof("foo"), &foo);
-	/* foo->type is the type and foo->value is the value */
-}
-
-
-php4_read()
-{
-	pval **foo;
-
-	_php3_hash_find(ht, "foo", sizeof("foo"), &foo);
-	/* (*foo)->type is the type and (*foo)->value is the value */
-}
-
---
-
-php3_write()
-{
-	pval newval;
-
-	newval.type = ...;
-	newval.value = ...;
-	_php3_hash_update(ht, "bar", sizeof("bar"), &newval, sizeof(pval), NULL);
-}
-
-php4_write()
-{
-	pval *newval = ALLOC_ZVAL();
-
-	newval->refcount=1;
-	newval->is_ref=0;
-	newval->type = ...;
-	newval->value = ...;
-	_php3_hash_update(ht, "bar", sizeof("bar"), &newval, sizeof(pval *), NULL);
-}
-
-
-[2]  Resources
-
-One of the 'cute' things about the reference counting support is that it
-completely eliminates the problem of resource leaking.  A simple loop that
-included '$result = mysql_query(...)' in PHP leaked unless the user
-remembered to run mysql_free($result) at the end of the loop body, and
-nobody really did.  In order to take advantage of the automatic resource
-deallocation upon destruction, there's virtually one small change you need
-to conduct.  Change the result type of a resource that you want to destroy
-itself as soon as its no longer referenced (just about any resource I can
-think of) as IS_RESOURCE, instead of as IS_LONG.  The rest is magic.
-
-A special treatment is required for SQL modules that follow MySQL's
-approach for having the link handle as an optional argument.  Modules that
-follow the MySQL module model, store the last opened link in a global
-variable, that they use in case the user neglects to explicitly specify a
-link handle.  Due to the way referenec counting works, this global
-reference is just like any other reference, and must increase that SQL link
-resource's reference count (otherwise, it will be closed prematurely).
-Simply, when you set the default link to a certain link, increase that
-link's reference count by calling zend_list_addref().
-As always, the MySQL module is the one used to demonstrate 'new
-technology'.  You can look around it and look for IS_RESOURCE, as well as
-zend_list_addref(), to see a clear example of how the new API should be used.
-
-
-[3]  Thread safety issues
-
-I'm not going to say that Zend was designed with thread safety in mind, but
-from some point, we've decided upon several guidelines that would make the
-move to thread safety much, much easier.  Generally, we've followed the PHP
-3.1 approach of moving global variables to a structure, and encapsulating
-all global variable references within macros.  There are three main
-differences:
-1.  We grouped related globals in a single structure, instead of grouping
-all globals in one structure.
-2.  We've used much, much shorter macro names to increase the readability
-of the source code.
-3.  Regardless of whether we're compiling in thread safe mode or not, all
-global variables are *always* stored in a structure.  For example, you
-would never have a global variable 'foo', instead, it'll be a property of a
-global structure, for example, compiler_globals.foo.  That makes
-development much, much easier, since your code will simply not compile
-unless you remember to put the necessary macro around foo.
-
-To write code that'll be thread safe in the future (when we release our
-thread safe memory manager and work on integrating it), you can take a look
-at zend_globals.h.  Essentially, two sets of macros are defined, one for
-thread safe mode, and one for thread unsafe mode.  All global references
-are encapsulated within ???G(varname), where ??? is the appropriate prefix
-for your structure (for example, so far we have CG(), EG() and AG(), which
-stand for the compiler, executor and memory allocator, respectively).
-When compiling with thread safety enabled, each function that makes use of
-a ???G() macro, must obtain the pointer to its copy of the structure.  It
-can do so in one of two forms:
-1.  It can receive it as an argument.
-2.  It can fetch it.
-
-Obviously, the first method is preferable since it's much quicker.
-However, it's not always possible to send the structure all the way to a
-particular function, or it may simply bloat the code too much in some
-cases.  Functions that receive the globals as an argument, should look like
-this:
-
-rettype functioname(???LS_D)			<-- a function with no arguments
-rettype functioname(type arg1, ..., type argn ???LS_DC)	<-- a funciton with
-arguments
-
-Calls to such functions should look like this:
-functionname(???LS_C)				<-- a function with no arguments
-functionname(arg1, ..., argn ???LS_CC)		<-- a function with arguments
-
-LS stands for 'Local Storage', _C stands for Call and _CC stands for Call
-Comma, _D stands for Declaration and _DC stands for Declaration Comma.
-Note that there's NO comma between the last argument and ???LS_DC or ???LS_CC.
-
-In general, every module that makes use of globals should use this approach
-if it plans to be thread safe.
-
-
-[4]  Generalized INI support
-
-The code comes to solve several issues:
-
-a.  The ugly long block of code in main.c that reads values from the
-cfg_hash into php3_ini.
-b.  Get rid of php3_ini.  The performance penalty of copying it around all
-the time in the Apache module probably wasn't too high, but
-psychologically, it annoyed me :)
-c.  Get rid of the ugly code in mod_php4.c, that also reads values from
-Apache directives and puts them into the php3_ini structure.
-d.  Generalize all the code so that you only have to add an entry in one
-single place and get it automatically supported in php3.ini, Apache, Win32
-registry, runtime function ini_get() and ini_alter() and any future method
-we might have.
-e.  Allow users to easily override *ANY* php3.ini value, except for ones
-they're not supposed to, of course.
-
-I'm happy to say that I think I pretty much reached all goals.  php_ini.c
-implements a mechanism that lets you add your INI entry in a single place,
-with a default value in case there's no php3.ini value.  What you get by
-using this mechanism:
-
-1.  Automatic initialization from php3.ini if available, or from the
-default value if not.
-2.  Automatic support in ini_alter().  That means a user can change the
-value for this INI entry at runtime, without you having to add in a single
-line of code, and definitely no additional function (for example, in PHP3,
-we had to add in special dedicated functions, like
-set_magic_quotes_runtime() or the likes - no need for that anymore).
-3.  Automatic support in Apache .conf files.
-4.  No need for a global php3_ini-like variable that'll store all that
-info.  You can directly access each INI entry by name, in runtime.  'Sure,
-that's not revolutionary, it's just slow' is probably what some of you
-think - which is true, but, you can also register a callback function that
-is called each time your INI entry is changed, if you wish to store it in a
-cached location for intensive use.
-5.  Ability to access the current active value for a given INI entry, and
-the 'master' value.
-
-Of course, (2) and (3) are only applicable in some cases.  Some entries
-shouldn't be overriden by users in runtime or through Apache .conf files -
-you can, of course, mark them as such.
-
-
-So, enough hype, how does it work.
-
-Essentially:
-
-static PHP_INI_MH(OnChangeBar);	/* declare a message handler for a change
-in "bar" */
-
-PHP_INI_BEGIN()
-	PHP_INI_ENTRY("foo",	"1",	PHP_INI_ALL,		NULL,		NULL)
-	PHP_INI_ENTRY("bar",	"bah",	PHP_INI_SYSTEM,	OnChangeBar,	NULL)
-PHP_INI_END()
-
-static PHP_INI_MH(OnChangeBar)
-{
-	a_global_var_for_bar = new_value;
-	return SUCCESS;
-}
-
-int whatever_minit(INIT_FUNC_ARGS)
-{	
-	...
-	REGISTER_INI_ENTRIES();
-	...
-}	
-
-
-int whatever_mshutdown(SHUTDOWN_FUNC_ARGS)
-{
-	...
-	UNREGISTER_INI_ENTRIES();
-	...
-}
-
-
-and that's it.  Here's what it does.  As you can probably guess, this code
-registers two INI entries - "foo" and "bar".  They're given defaults "1"
-and "bah" respectively - note that all defaults are always given as
-strings.  That doesn't reduce your ability to use integer values, simply
-specify them as strings.  "foo" is marked so that it can be changed by
-anyone at any time (PHP_INI_ALL), whereas "bar" is marked so it can be
-changed only at startup in the php3.ini only, presumably, by the system
-administrator (PHP_INI_SYSTEM).
-When "foo" changes, no function is called.  Access to it is done using the
-macros INI_INT("foo"), INI_FLT("foo") or INI_STR("foo"), which return a
-long, double or char * respectively (strings that are returned aren't
-duplicated - if they're manipulated, you must duplicate them first).  You
-can also access the original value (the 'master' value, in case one of them
-was overriden by a user) using another pair of macros:
-INI_ORIG_INT("foo"), INI_ORIG_FLT("foo") and INI_ORIG_STR("foo").
-
-When "bar" changes, a special message handler is called, OnBarChange().
-Always declare those message handlers using PHP_INI_MH(), as they might
-change in the future.  Message handlers are called as soon as an ini entry
-initializes or changes, and allow you to cache a certain INI value in a
-quick C structure.  In this example, whenever "bar" changes, the new value
-is stored in a_global_var_for_bar, which is a global char * pointer,
-quickly accessible from other functions.  Things get a bit more complicated
-when you want to implement a thread-safe module, but it's doable as well.
-Message handlers may return SUCCESS to acknowledge the new value, or
-FAILURE to reject it.  That enables you to reject invalid values for some
-INI entries if you want.  Finally, you can have a pointer passed to your
-message handler - that's the fifth argument to PHP_INI_ENTRY().  It is
-passed as mh_arg to the message handler.
-
-Remember that for certain values, there's really no reason to mess with a
-callback function.  A perfect example for this are the syntax highlight
-colors, which no longer have a dedicated global C slot that stores them,
-but instead, are fetched from the php_ini hash on demand.
-
-"As always", for a perfect working example of this mechanism, consult
-functions/mysql.c.  This module uses the new INI entry mechanism, and was
-also converted to be thread safe in general, and in its php_ini support in
-particular.  Converting your modules to look like this for thread safety
-isn't a bad idea (not necessarily now, but in the long run).

----------------- 
-
-1. Function Prototype
-
-   All functions look like this:
-
-       PHP_FUNCTION(foo) {
-
-       }
-
-   Even if your function doesn't take any arguments, this is how it is
-   called.
-
-----------------
-
-2. Function Arguments
-
-   Arguments are always of type pval.  This type contains a union which
-   has the actual type of the argument.  So, if your function takes two
-   arguments, you would do something like the following at the top of your
-   function:
-
-       pval *arg1, *arg2;
-       if (ARG_COUNT(ht) != 2 || getParameters(ht,2,&arg1,&arg2)==FAILURE) {
-           WRONG_PARAM_COUNT;
-       }
-
-   NOTE: Arguments can be passed either by value or by reference. In both
-   cases you will need to pass &(pval *) to getParameters. If you want to
-   check if the n'th parameter was sent to you by reference or not, you can
-   use the function, ParameterPassedByReference(ht,n). It will return either
-   1 or 0.
-
-   When you change any of the passed parameters, whether they are sent by
-   reference or by value, you can either start over with the parameter by
-   calling pval_destructor on it, or if it's an ARRAY you want to add to,
-   you can use functions similar to the ones in internal_functions.h which
-   manipulate return_value as an ARRAY.
-
-   Also if you change a parameter to IS_STRING make sure you first assign
-   the new estrdup'ed string and the string length, and only later change the
-   type to IS_STRING. If you change the string of a parameter which already
-   IS_STRING or IS_ARRAY you should run pval_destructor on it first.
-   
-----------------
-
-3. Variable number of function arguments
-
-   A function can take a variable number of arguments.  If your function can
-   take either 2 or 3 arguments, use the following:
-
-       pval *arg1, *arg2, *arg3;
-       int arg_count = ARG_COUNT(ht);
-
-       if (arg_count<2 || arg_count>3 ||
-           getParameters(ht,arg_count,&arg1,&arg2,&arg3)==FAILURE) {
-           WRONG_PARAM_COUNT;
-       }
-
------------------
-
-4. Using the function arguments
-
-   The type of each argument is stored in the pval type field:
-
-
-   This type can be any of the following:
-
-       IS_STRING             String
-       IS_DOUBLE             Double-precision floating point
-       IS_LONG               Long
-       IS_ARRAY              Array
-
-       IS_EMPTY              ??
-       IS_USER_FUNCTION      ??
-       IS_INTERNAL_FUNCTION  ?? (if some of these cannot be passed to a
-                                 function - delete)
-       IS_CLASS              ??
-       IS_OBJECT             ??
-       
-   If you get an argument of one type and would like to use it as another,
-   or if you just want to force the argument to be of a certain type, you
-   can use one of the following conversion functions:
-
-       convert_to_long(arg1);
-       convert_to_double(arg1);
-       convert_to_string(arg1); 
-       convert_to_boolean_long(arg1);    If the string is "" or "0" it
-                                         becomes 0, 1 otherwise
-       convert_string_to_number(arg1);   Converts string to either LONG or
-                                         DOUBLE depending on string
-
-   These function all do in-place conversion.  They do not return anything.
-
-   The actual argument is stored in a union.  
-
-   For type IS_STRING, use arg1->value.str.val
-            IS_LONG        arg1->value.lval
-            IS_DOUBLE      arg1->value.dval
- 
-------------------
-
-5. Memory management in functions
-
-   Any memory needed by a function should be allocated with either emalloc()
-   or estrdup().  These are memory handling abstraction functions that look
-   and smell like the normal malloc() and strdup() functions.  Memory should
-   be freed with efree().
-
-   There are two kinds of memory in this program. Memory which is returned
-   to the parser in a variable and memory which you need for temporary
-   storage in your internal function.  When you assign a string to a
-   variable which is returned to the parser you need to make sure you first
-   allocate the memory with either emalloc or estrdup.  This memory
-   should NEVER be freed by you, unless you later, in the same function
-   overwrite your original assignment (this kind of programming practice is
-   not good though).
-
-   For any temporary/permanent memory you need in your functions/library you
-   should use the three emalloc(), estrdup(), and efree() functions. They
-   behave EXACTLY like their counterpart functions. Anything you emalloc()
-   or estrdup() you have to efree() at some point or another, unless it's
-   supposed to stick around until the end of the program, otherwise there
-   will be a memory leak. The meaning of "the functions behave exactly like
-   their counterparts" is if you efree() something which was not
-   emalloc()'ed nor estrdup()'ed you might get a segmentation fault. So
-   please take care and free all of your wasted memory. One of the biggest
-   improvements in PHP 3.0 will hopefully be the memory management.
-
-   If you compile with "-DDEBUG", PHP3 will print out a list of all
-   memory that was allocated using emalloc() and estrdup() but never
-   freed with efree() when it is done running the specified script.
-
-------------------
-
-6. Setting variables in the symbol table
-
-   A number of macros are available which make it easier to set a variable
-   in the symbol table:
-
-       SET_VAR_STRING(name,value) **
-       SET_VAR_DOUBLE(name,value)
-       SET_VAR_LONG(name,value)
-
-   ** Be careful here.  The value part must be malloc'ed manually because
-      the memory management code will try to free this pointer later.  Do
-      not pass statically allocated memory into a SET_VAR_STRING
-
-  Symbol tables in PHP 3.0 are implemented as hash tables.  At any given time,
-  &symbol_table is a pointer to the 'main' symbol table, and active_symbol_table
-  points to the currently active symbol table (these may be identical like in
-  startup, or different, if you're inside a function).
-  
-  The following examples use 'active_symbol_table'.  You should replace it with
-  &symbol_table if you specifically want to work with the 'main' symbol table.
-  Also, the same funcions may be applied to arrays, as explained below.
-  
-  * To check whether a variable named $foo already exists in a symbol table:
-    if (hash_exists(active_symbol_table,"foo",sizeof("foo"))) { exists... }
-    else { doesn't exist }
-  
-  * If you also need to get the type of the variable, you can use:
-    hash_find(active_symbol_table,"foo",sizeof("foo"),&pvalue);
-    check(pvalue.type);
-  
-  Arrays in PHP 3.0 are implemented using the same hashtables as symbol tables.
-  This means the two above functions can also be used to check variables
-  inside arrays.
-
-  If you want to define a new array in a symbol table, you should do this:
-
-      1.  Possibly check it exists and abort, using hash_exists()
-          or hash_find().
-      2.  Code:
-  
-      pval arr;
-  
-      if (array_init(&arr) == FAILURE) { failed... };
-      hash_update(active_symbol_table,"foo",sizeof("foo"),&arr,sizeof(pval),NULL);
-  
-  This code declares a new array, named $foo, in the active symbol table.
-  This array is empty.
-  
-  Here's how to add new entries to it:
-  
-      pval entry;
-  
-      entry.type = IS_LONG;
-      entry.value.lval = 5;
-  
-      hash_update(arr.value.ht,"bar",sizeof("bar"),&entry,sizeof(pval),NULL); /* defines $foo["bar"] = 5 */
-      hash_index_update(arr.value.ht,7,&entry,sizeof(pval),NULL); /* defines $foo[7] = 5 */
-      hash_next_index_insert(arr.value.ht,&entry,sizeof(pval),NULL); /* defines the next free place in $foo[],
-                                                                         * $foo[8], to be 5 (works like php2)
-                                                                         */
-  
-  If you'd like to modify a value that you inserted to a hash, you must first retreive it from the hash.  To
-  prevent that overhead, you can supply a pval ** to the hash add function, and it'll be updated with the
-  pval * address of the inserted element inside the hash.  If that value is NULL (like in all of the
-  above examples) - that parameter is ignored.
-
-  hash_next_index_insert() works more or less using the same logic
-  "$foo[] = bar;" works in PHP 2.0.
-
-  If you are building an array to return from a function, you can initialize
-  the array just like above by doing:
-
-    if (array_init(return_value) == FAILURE) { failed...; }
-
-  and then adding values with the helper functions:
-
-    add_next_index_long(return_value,long_value);
-    add_next_index_double(return_value,double_value);
-    add_next_index_string(return_value,estrdup(string_value));
-  
-  Of course, if the adding isn't done right after the array
-  initialization, you'd probably have to look for the array first:
-  
-    pval *arr;
-  
-    if (hash_find(active_symbol_table,"foo",sizeof("foo"),(void **)&arr)==FAILURE) { can't find... }
-    else { use arr->value.ht... }
-  
-  Note that hash_find receives a pointer to a pval pointer, and
-  not a pval pointer.
-  
-  Just about any hash function returns SUCCESS or FAILURE (except for
-  hash_exists() that returns a boolean truth value).
-    
-------------------
-
-7. Returning 'simple' values from functions (integers, floats or strings)
-
-   A number of macros are available to make it easier to return things from
-   functions:
-
-   These set the return value and return from the function:
-
-   RETURN_FALSE
-   RETURN_TRUE
-   RETURN_LONG(l)
-   RETURN_STRING(s,dup)        If dup is true, duplicates the string
-   RETURN_STRINGL(s,l,dup)     Return string (s) specifying length (l).
-   RETURN_DOUBLE(d)
-
-   These only set the return value:
-
-   RETVAL_FALSE
-   RETVAL_TRUE
-   RETVAL_LONG(l)
-   RETVAL_STRING(s,dup)       If dup is true, duplicates the string
-   RETVAL_STRINGL(s,l,dup)    Return string (s) specifying length (l).
-   RETVAL_DOUBLE(d)
-
-   The string macros above will all estrdup() the passed 's' argument,
-   so you can safely free the argument after calling the macro, or
-   alternatively use statically allocated memory.
-
-   If your function returns boolean success/error responses, always use
-   RETURN_TRUE and RETURN_FALSE respectively.
-
-------------------
-
-8. Returning 'complex' values from functions (arrays or objects)
-
-   Your function can also return a complex data type such as an object
-   or an array.
-
-   Returning an object:
-
-   1. Call object_init(return_value).
-   2. Fill it up with values:
-
-   add_property_long(return_value,property_name,l)			Add a property named 'property_name', of type long, equals to 'l'
-   add_property_double(return_value,property_name,d)		Same, only a double
-   add_property_string(return_value,property_name,str)		Same, only a string
-   add_property_stringl(return_value,property_name,str,l)	Add a property named 'property_name', of type string, string is 'str' with length 'l'
-
-   3. Possibly, register functions for this object.  In order to
-      obtain values from the object, the function would have to fetch
-      "this" from the active_symbol_table.  Its type should be IS_OBJECT,
-      and it's basically a regular hash table (i.e., you can use regular
-      hash functions on .value.ht).  The actual registration of the
-      function can be done using:
-   
-   add_method(return_value,function_name,function_ptr)
-   
-   
-   Returning an array:
-
-   1.  Call array_init(return_value).
-   2.  Fill it up with values:
-
-   add_assoc_long(return_value,key,l)				add associative entry with key 'key' and long value 'l'
-   add_assoc_double(return_value,key,d)		
-   add_assoc_string(return_value,key,str)
-   add_assoc_stringl(return_value,key,str,length)	specify the string length
-
-   add_index_long(return_value,index,l)				add entry in index 'index' with long value 'l'
-   add_index_double(return_value,index,d)
-   add_index_string(return_value,index,str)
-   add_index_stringl(return_value,index,str,length)  specify the string length
-
-   add_next_index_long(return_value,l)				add an array entry in the next free offset with long value 'l'
-   add_next_index_double(return_value,d)
-   add_next_index_string(return_value,str)
-   add_next_index_stringl(return_value,str,length)	specify the string length
-
-------------------
-
-9. Using the resource list
-
-   PHP 3.0 has a standard way of dealing with various types of resources,
-   that replaces all of the local linked lists in PHP 2.0.
-
-   Available functions:
-
-   php3_list_insert(ptr, type)      returns the 'id' of the newly inserted resource
-   php3_list_delete(id)             delete the resource with the specified id
-   php3_list_find(id,*type)         returns the pointer of the resource with the specified id, updates 'type' to the resource's type
-
-   Typically, these functions are used for SQL drivers but they can be
-   used for anything else, and are used, for instance, for maintaining
-   file descriptors.
-
-   Typical list code would look like this:
-
-	Adding a new resource:
-
-		RESOURCE *resource;
-
-		...allocate memory for resource and acquire resource...
-		/* add a new resource to the list */
-		return_value->value.lval = php3_list_insert((void *) resource, LE_RESOURCE_TYPE);
-		return_value->type = IS_LONG;
-
-	Using an existing resource:
-
-		pval *resource_id;
-		RESOURCE *resource;
-		int type;
-
-		convert_to_long(resource_id);
-		resource = php3_list_find(resource_id->value.lval, &type);
-		if (type != LE_RESOURCE_TYPE) {
-			php3_error(E_WARNING,"resource index %d has the wrong type",resource_id->value.lval);
-			RETURN_FALSE;
-		}
-		...use resource...
-
-	Deleting an existing resource:
-
-		pval *resource_id;
-		RESOURCE *resource;
-		int type;
-
-		convert_to_long(resource_id);
-		php3_list_delete(resource_id->value.lval);
-   
-
-   The resource types should be registered in php3_list.h, in enum
-   list_entry_type.  In addition, one should add shutdown code for any
-   new resource type defined, in list.c's list_entry_destructor() (even if
-   you don't have anything to do on shutdown, you must add an empty case).
-
-------------------
-
-10. Using the persistent resource table
-
-   PHP 3.0 has a standard way of storing persistent resources (i.e.,
-   resources that are kept in between hits).  The first module to use
-   this feature was the MySQL module, and mSQL followed it, so one can
-   get the general impression of how a persistent resource should be
-   used by reading mysql.c.  The functions you should look at are:
-   php3_mysql_do_connect()
-   php3_mysql_connect()
-   php3_mysql_pconnect()
-
-   The general idea of persistence modules is this:
-   1.  Code all of your module to work with the regular resource list
-       mentioned in section (9).
-   2.  Code extra connect functions that check if the resource already
-       exists in the persistent resource list.  If it does, register it
-       as in the regular resource list as a pointer to the persistent
-       resource list (because of 1., the rest of the code
-       should work immediately).  If it doesn't, then create it, add it
-       to the persistent resource list AND add a pointer to it from the
-       regular resource list, so all of the code would work since it's
-       in the regular resource list, but on the next connect, the
-       resource would be found in the persistent resource list and be
-       used without having to recreate it.
-       You should register these resources with a different type (e.g.
-       LE_MYSQL_LINK for non-persistent link and LE_MYSQL_PLINK for
-       a persistent link).
-
-   If you read mysql.c, you'll notice that except for the more complex
-   connect function, nothing in the rest of the module has to be changed.
-   
-   The very same interface exists for the regular resource list and the
-   persistent resource list, only 'list' is replaced with 'plist':
-
-   php3_plist_insert(ptr, type)      returns the 'id' of the newly inserted resource
-   php3_plist_delete(id)             delete the resource with the specified id
-   php3_plist_find(id,*type)         returns the pointer of the resource with the specified id, updates 'type' to the resource's type
-
-   However, it's more than likely that these functions would prove
-   to be useless for you when trying to implement a persistent module.
-   Typically, one would want to use the fact that the persistent resource
-   list is really a hash table.  For instance, in the MySQL/mSQL modules,
-   when there's a pconnect() call (persistent connect), the function
-   builds a string out of the host/user/passwd that were passed to the
-   function, and hashes the SQL link with this string as a key.  The next
-   time someone calls a pconnect() with the same host/user/passwd, the
-   same key would be generated, and the function would find the SQL link
-   in the persistent list.
-
-   Until further documented, you should look at mysql.c or msql.c to
-   see how one should use the plist's hash table abilities.
-
-   One important thing to note:  resources going into the persistent
-   resource list must *NOT* be allocated with PHP's memory manager, i.e.,
-   they should NOT be created with emalloc(), estrdup(), etc.  Rather,
-   one should use the regular malloc(), strdup(), etc.  The reason for
-   this is simple - at the end of the request (end of the hit), every
-   memory chunk that was allocated using PHP's memory manager is deleted.
-   Since the persistent list isn't supposed to be erased at the end
-   of a request, one mustn't use PHP's memory manager for allocating
-   resources that go to it.
-
-   Shutting down persistent resources:  
-   
-   When you register resource that's going to be in the persistent list,
-   you should add destructors to it both in the non-persistent list
-   and in the persistent list.
-   The destructor in the non-persistent list destructor shouldn't do anything.
-   The one in the persistent list destructor should properly free any
-   resources obtained by that type (e.g. memory, SQL links, etc).  Just like
-   with the non-persistent resources, you *MUST* add destructors for every
-   resource, even it requires no destructotion and the destructor would
-   be empty.
-   Remember, since emalloc() and friends aren't to be used in conjunction
-   with the persistent list, you mustn't use efree() here either.
-
-------------------
-
-11. Adding runtime configuration directives
-
-Many of the features of PHP3 can be configured at runtime.  These
-configuration directives can appear in either the designated php3.ini
-file, or in the case of the Apache module version in the Apache .conf
-files.  The advantage of having them in the Apache .conf files is that
-they can be configured on a per-directory basis.  This means that one
-directory may have a certain safemodeexecdir for example, while another
-directory may have another.  This configuration granularity is especially
-handy when a server supports multiple virtual hosts.
-
-The steps required to add a new directive:
-
- 1. Add directive to php3_ini_structure struct in mod_php4.h. 
-    
- 2. In main.c, edit the php3_module_startup function and add the
-    appropriate cfg_get_string() or cfg_get_long() call.
-
- 3. Add the directive, restrictions and a comment to the php3_commands
-    structure in mod_php4.c.  Note the restrictions part.  RSRC_CONF are
-    directives that can only be present in the actual Apache .conf files.
-    Any OR_OPTIONS directives can be present anywhere, include normal
-    .htaccess files.
-
- 4. In either php3take1handler() or php3flaghandler() add the appropriate
-    entry for your directive.
-
- 5. In the configuration section of the _php3_info() function in
-    functions/info.c you need to add your new directive.
-
- 6. And last, you of course have to use your new directive somewhere.
-    It will be addressable as php3_ini.directive

-                       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-                            Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations
-below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-^L
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it
-becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-^L
-                  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control
-compilation
-and installation of the library.

-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-^L
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-^L
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-^L
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-^L
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply, and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License
-may add an explicit geographical distribution limitation excluding those
-countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-^L
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-                            NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-^L
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms
-of the ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.
-It is safest to attach them to the start of each source file to most
-effectively convey the exclusion of warranty; and each file should
-have at least the "copyright" line and a pointer to where the full
-notice is found.
-
-
-    <one line to give the library's name and a brief idea of what it
-does.>
-    Copyright (C) <year>  <name of author>

-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.

-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307  USA
-
-Also add information on how to contact you by electronic and paper
-mail.
-
-You should also get your employer (if you work as a programmer) or
-your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the

-BCMATH FAQ: 
-
-1) Why BCMATH?
-
-The math routines of GNU bc become more generally useful in a
-library form.  By separating the BCMATH library from GNU bc,
-GNU bc can be under the GPL and BCMATH can be under the LGPL.
-
-2) Why BCMATH when GMP exists?
-
-GMP has "integers" (no digits after a decimal), "rational numbers"
-(stored as 2 integers) and "floats".  None of these will correctly
-represent a POSIX BC number.  Floats are the closest, but will not
-behave correctly for many computations.  For example, BC numbers have
-a "scale" that represent the number of digits to represent after the
-decimal point.  The multiplying two of these numbers requires one to
-calculate an exact number of digits after the decimal point regardless
-of the number of digits in the integer part.  GMP floats have a
-"fixed, but arbitrary" mantissa and so multiplying two floats will end
-up dropping digits BC must calculate.
