+
+The General Public License (GPL)
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
+Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
+verbatim copies of this license document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to share
+and change it. By contrast, the GNU General Public License is intended to
+guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to most of
+the Free Software Foundation's software and to any other program whose
+authors commit to using it. (Some other Free Software Foundation software is
+covered by the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+When we speak of free software, we are referring to freedom, 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 or use pieces of it in new free programs; and that you know you can do
+these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny
+you these rights or to ask you to surrender the rights. These restrictions
+translate to certain responsibilities for you if you distribute copies of the
+software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for a
+fee, you must give the recipients all the rights that you have. You must make
+sure that they, too, receive or can get the source code. And you must show
+them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2) offer
+you this license which gives you legal permission to copy, distribute and/or
+modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If the
+software is modified by someone else and passed on, we want its recipients to
+know that what they have is not the original, so that any problems introduced by
+others will not reflect on the original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We wish
+to avoid the danger that redistributors of a free program will individually obtain
+patent licenses, in effect making the program proprietary. To prevent this, we
+have made it clear that any patent must be licensed for everyone's free use or
+not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+GNU GENERAL PUBLIC LICENSE
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
+MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+placed by the copyright holder saying it may be distributed under the terms of
+this General Public License. The "Program", below, refers to any such program
+or work, and a "work based on the Program" means either the Program or any
+derivative work under copyright law: that is to say, a work containing the
+Program or a portion of it, either verbatim or with modifications and/or translated
+into another language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered by
+this License; they are outside its scope. The act of running the Program is not
+restricted, and the output from the Program is covered only if its contents
+constitute a work based on the Program (independent of having been made by
+running the Program). Whether that is true depends on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's 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 give any other recipients of the Program a copy of this License
+along with the Program.
+
+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 Program or any portion of it, thus
+forming a work based on the Program, 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) You must cause the modified files to carry prominent notices stating that you
+changed the files and the date of any change.
+
+b) You must cause any work that you distribute or publish, that in whole or in
+part contains or is derived from the Program or any part thereof, to be licensed
+as a whole at no charge to all third parties under the terms of this License.
+
+c) If the modified program normally reads commands interactively when run, you
+must cause it, when started running for such interactive use in the most ordinary
+way, to print or display an announcement including an appropriate copyright
+notice and a notice that there is no warranty (or else, saying that you provide a
+warranty) and that users may redistribute the program under these conditions,
+and telling the user how to view a copy of this License. (Exception: if the
+Program itself is interactive but does not normally print such an announcement,
+your work based on the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If identifiable
+sections of that work are not derived from the Program, 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 Program, 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 Program.
+
+In addition, mere aggregation of another work not based on the Program with the
+Program (or with a work based on the Program) on a volume of a storage or
+distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+Section 2) in object code or executable form under the terms of Sections 1 and 2
+above provided that you also do one of the following:
+
+a) 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; or,
+
+b) Accompany it with a written offer, valid for at least three years, to give any
+third party, for a charge no more than your cost of physically performing source
+distribution, a complete machine-readable copy of the corresponding source
+code, to be distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange; or,
+
+c) Accompany it with the information you received as to the offer to distribute
+corresponding source code. (This alternative is allowed only for noncommercial
+distribution and only if you received the program in object code or executable
+form with such an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for making
+modifications to it. For an executable work, 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
+executable. However, as a special exception, the source code 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.
+
+If distribution of executable or 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 counts as distribution of the source code, even though
+third parties are not compelled to copy the source along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+expressly provided under this License. Any attempt otherwise to copy, modify,
+sublicense or distribute the Program 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.
+
+5. 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 Program
+or its derivative works. These actions are prohibited by law if you do not accept
+this License. Therefore, by modifying or distributing the Program (or any work
+based on the Program), you indicate your acceptance of this License to do so,
+and all its terms and conditions for copying, distributing or modifying the
+Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the Program),
+the recipient automatically receives a license from the original licensor to copy,
+distribute or modify the Program 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
+to this License.
+
+7. 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 Program at all. For example, if a patent license would
+not permit royalty-free redistribution of the Program 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
+Program.
+
+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.
+
+8. If the distribution and/or use of the Program is restricted in certain countries
+either by patents or by copyrighted interfaces, the original copyright holder who
+places the Program 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.
+
+9. The Free Software Foundation may publish revised and/or new versions of the
+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 Program 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 Program does
+not specify a version number of this License, you may choose any version ever
+published by the Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+whose distribution conditions are different, 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
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS
+NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
+COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
+"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
+PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
+YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+12. 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 PROGRAM 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 PROGRAM
+(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 PROGRAM TO OPERATE WITH ANY
+OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

+The Artistic License
+
+Preamble
+
+The intent of this document is to state the conditions under which a Package
+may be copied, such that the Copyright Holder maintains some semblance of
+artistic control over the development of the package, while giving the users of the
+package the right to use and distribute the Package in a more-or-less customary
+fashion, plus the right to make reasonable modifications.
+
+Definitions:
+
+-    "Package" refers to the collection of files distributed by the Copyright
+     Holder, and derivatives of that collection of files created through textual
+     modification. 
+-    "Standard Version" refers to such a Package if it has not been modified,
+     or has been modified in accordance with the wishes of the Copyright
+     Holder. 
+-    "Copyright Holder" is whoever is named in the copyright or copyrights for
+     the package. 
+-    "You" is you, if you're thinking about copying or distributing this Package.
+-    "Reasonable copying fee" is whatever you can justify on the basis of
+     media cost, duplication charges, time of people involved, and so on. (You
+     will not be required to justify it to the Copyright Holder, but only to the
+     computing community at large as a market that must bear the fee.) 
+-    "Freely Available" means that no fee is charged for the item itself, though
+     there may be fees involved in handling the item. It also means that
+     recipients of the item may redistribute it under the same conditions they
+     received it. 
+
+1. You may make and give away verbatim copies of the source form of the
+Standard Version of this Package without restriction, provided that you duplicate
+all of the original copyright notices and associated disclaimers.
+
+2. You may apply bug fixes, portability fixes and other modifications derived from
+the Public Domain or from the Copyright Holder. A Package modified in such a
+way shall still be considered the Standard Version.
+
+3. You may otherwise modify your copy of this Package in any way, provided
+that you insert a prominent notice in each changed file stating how and when
+you changed that file, and provided that you do at least ONE of the following:
+
+     a) place your modifications in the Public Domain or otherwise
+     make them Freely Available, such as by posting said modifications
+     to Usenet or an equivalent medium, or placing the modifications on
+     a major archive site such as ftp.uu.net, or by allowing the
+     Copyright Holder to include your modifications in the Standard
+     Version of the Package.
+
+     b) use the modified Package only within your corporation or
+     organization.
+
+     c) rename any non-standard executables so the names do not
+     conflict with standard executables, which must also be provided,
+     and provide a separate manual page for each non-standard
+     executable that clearly documents how it differs from the Standard
+     Version.
+
+     d) make other distribution arrangements with the Copyright Holder.
+
+4. You may distribute the programs of this Package in object code or executable
+form, provided that you do at least ONE of the following:
+
+     a) distribute a Standard Version of the executables and library
+     files, together with instructions (in the manual page or equivalent)
+     on where to get the Standard Version.
+
+     b) accompany the distribution with the machine-readable source of
+     the Package with your modifications.
+
+     c) accompany any non-standard executables with their
+     corresponding Standard Version executables, giving the
+     non-standard executables non-standard names, and clearly
+     documenting the differences in manual pages (or equivalent),
+     together with instructions on where to get the Standard Version.
+
+     d) make other distribution arrangements with the Copyright Holder.
+
+5. You may charge a reasonable copying fee for any distribution of this Package.
+You may charge any fee you choose for support of this Package. You may not
+charge a fee for this Package itself. However, you may distribute this Package in

+this Package as a product of your own.
+
+6. The scripts and library files supplied as input to or produced as output from
+the programs of this Package do not automatically fall under the copyright of this
+Package, but belong to whomever generated them, and may be sold
+commercially, and may be aggregated with this Package.
+
+7. C or perl subroutines supplied by you and linked into this Package shall not
+be considered part of this Package.
+
+8. The name of the Copyright Holder may not be used to endorse or promote
+products derived from this software without specific prior written permission.

+NAME
+    prefork - Optimized module loading for forking or non-forking processes
+
+SYNOPSIS
+    In a module that normally delays module loading with require
+
+      # Module Foo::Bar only uses This::That 25% of the time.
+      # We want to preload in in forking scenarios (like mod_perl), but
+      # we want to delay loading in non-forking scenarios (like CGI)
+      use prefork 'This::That';
+      
+  sub do_something {
+          my $arg = shift;
+      
+      # Load the module at run-time as normal
+          if ( $special_case ) {
+              require This::That;
+              This::That::blah(@_);
+          }
+      }
+      
+  # Register a module to be loaded before forking directly
+      prefork::prefork('Module::Name');
+
+    In a script or module that is going to be forking.
+
+      package Module::Forker;
+      
+  # Enable forking mode
+      use prefork ':enable';
+      
+  # Or call it directly
+      prefork::enable();
+
+    In a third-party run-time loader
+
+      package Runtime::Loader;
+      
+  use prefork ();
+      prefork::notify( \&load_everything );
+      
+  ...

+
+INTRODUCTION
+    The task of optimizing module loading in Perl tends to move in two
+    different directions, depending on the context.
+
+    In a procedural context, such as scripts and CGI-type situations, you
+    can improve the load times and memory usage by loading a module at
+    run-time, only once you are sure you will need it.
+
+    In the other common load profile for perl applications, the application
+    will start up and then fork off various worker processes. To take full
+    advantage of memory copy-on-write features, the application should load
+    as many modules as possible before forking to prevent them consuming
+    memory in multiple worker processes.
+
+    Unfortunately, the strategies used to optimise for these two load
+    profiles are diametrically opposed. What improves a situation for one
+    tends to make life worse for the other.
+
+DESCRIPTION
+    The "prefork" pragma is intended to allow module writers to optimise
+    module loading for both scenarios with as little additional code as
+    possible.
+
+    prefork.pm is intended to serve as a central and optional marshalling
+    point for state detection (are we running in compile-time or run-time
+    mode) and to act as a relatively light-weight module loader.
+
+  Loaders and Forkers
+    "prefork" is intended to be used in two different ways.
+
+    The first is by a module that wants to indicate that another module
+    should be loaded before forking. This is known as a "Loader".
+
+    The other is a script or module that will be initiating the forking. It
+    will tell prefork.pm that it is either going to fork, or is about to
+    fork, or for some other reason all modules previously mentioned by the
+    Loaders should be loaded immediately.
+
+  Usage as a Pragma
+    A Loader can register a module to be loaded using the following
+
+      use prefork 'My::Module';
+
+    The same thing can be done in such a way as to not require prefork being
+    installed, but taking advantage of it if it is.
+
+      eval "use prefork 'My::Module';";
+
+    A Forker can indicate that it will be forking with the following
+
+      use prefork ':enable';
+
+    In any use of "prefork" as a pragma, you can only pass a single value as
+    argument. Any additional arguments will be ignored. (This may throw an
+    error in future versions).
+
+  Compatbility with mod_perl and others
+    Part of the design of "prefork", and its minimalistic nature, is that it
+    is intended to work easily with existing modules, needing only small
+    changes.
+
+    For example, "prefork" itself will detect the $ENV{MOD_PERL} environment
+    variable and automatically start in forking mode.
+
+    prefork has support for integrating with third-party modules, such as
+    Class::Autouse. The "notify" function allows these run-time loaders to
+    register callbacks, to be called once prefork enters forking mode.
+
+    The synopsis entry above describes adding support for prefork.pm as a
+    dependency. To allow your third-party module loader without a dependency
+    and only if it is installed use the following:
+
+      eval { require prefork; }
+      prefork::notify( \&function ) unless $@;
+
+  Using prefork.pm
+    From the Loader side, it is fairly simple. prefork becomes a dependency
+    for your module, and you use it as a pragma as documented above.
+
+    For the Forker, you have two options. Use as a dependency or optional
+    use.
+
+    In the dependency case, you add prefork as a dependency and use it as a
+    pragma with the ':enable' option.
+
+    To add only optional support for prefork, without requiring it to be
+    installed, you should wait until the moment just before you fork and
+    then call "prefork::enable" directly ONLY if it is loaded.
+
+      # Load modules if any use the prefork pragma.
+      prefork::enable() if $INC{prefork.pm};
+
+    This will cause the modules to be loaded ONLY if there are any modules
+    that need to be loaded. The main advantage of the dependency version is
+    that you only need to enable the module once, and not before each fork.
+
+    If you wish to have your own module leverage off the forking-detection
+    that prefork provides, you can also do the following.
+
+      use prefork;
+      if ( $prefork::FORKING ) {
+          # Complete some preparation task
+      }
+
+  Modules that are prefork-aware
+    mod_perl/mod_perl2
+    Class::Autouse
+
+FUNCTIONS
+  prefork $module
+    The 'prefork' function indicates that a module should be loaded before
+    the process will fork. If already in forking mode the module will be
+    loaded immediately.
+
+    Otherwise it will be added to a queue to be loaded later if it recieves
+    instructions that it is going to be forking.
+
+    Returns true on success, or dies on error.
+
+  enable
+    The "enable" function indicates to the prefork module that the process
+    is going to fork, possibly immediately.
+
+    When called, prefork.pm will immediately load all outstanding modules,
+    and will set a flag so that any further 'prefork' calls will load the
+    module at that time.
+
+    Returns true, dieing as normal is there is a problem loading a module.
+
+  notify &function
+    The "notify" function is used to integrate support for modules other
+    than prefork.pm itself.
+
+    A module loader calls the notify function, passing it a reference to a
+    "CODE" reference (either anon or a function reference). "prefork" will
+    store this CODE reference, and execute it immediately as soon as it
+    knows it is in forking-mode, but after it loads its own modules.
+
+    Callbacks are called in the order they are registered.
+
+    Normally, this will happen as soon as the "enable" function is called.
+
+    However, you should be aware that if prefork is already in preforking
+    mode at the time that the notify function is called, prefork.pm will
+    execute the function immediately.
+
+    This means that any third party module loader should be fully loaded and
+    initialised before the callback is provided to "notify".
+
+    Returns true if the function is stored, or dies if not passed a "CODE"
+    reference, or the callback is already set in the notify queue.
+
+TO DO
+    - Add checks for more pre-forking situations

+
+prefork - Optimized module loading for forking or non-forking processes
+
+=head1 SYNOPSIS
+
+In a module that normally delays module loading with require
+
+  # Module Foo::Bar only uses This::That 25% of the time.
+  # We want to preload in in forking scenarios (like mod_perl), but
+  # we want to delay loading in non-forking scenarios (like CGI)
+  use prefork 'This::That';
+  
+  sub do_something {
+      my $arg = shift;
+  
+      # Load the module at run-time as normal
+      if ( $special_case ) {
+          require This::That;
+          This::That::blah(@_);
+      }
+  }
+  
+  # Register a module to be loaded before forking directly
+  prefork::prefork('Module::Name');
+
+In a script or module that is going to be forking.
+
+  package Module::Forker;
+  
+  # Enable forking mode
+  use prefork ':enable';
+  
+  # Or call it directly
+  prefork::enable();
+
+In a third-party run-time loader
+
+  package Runtime::Loader;
+  
+  use prefork ();
+  prefork::notify( \&load_everything );
+  
+  ...
+  
+  sub load_everything { ... }
+  
+  1;
+  
+=head1 INTRODUCTION
+
+The task of optimizing module loading in Perl tends to move in two different
+directions, depending on the context.
+
+In a procedural context, such as scripts and CGI-type situations, you can
+improve the load times and memory usage by loading a module at run-time,
+only once you are sure you will need it.
+
+In the other common load profile for perl applications, the application
+will start up and then fork off various worker processes. To take full
+advantage of memory copy-on-write features, the application should load
+as many modules as possible before forking to prevent them consuming memory
+in multiple worker processes.
+
+Unfortunately, the strategies used to optimise for these two load profiles
+are diametrically opposed. What improves a situation for one tends to
+make life worse for the other.
+
+=head1 DESCRIPTION
+
+The C<prefork> pragma is intended to allow module writers to optimise
+module loading for B<both> scenarios with as little additional code as
+possible.
+
+prefork.pm is intended to serve as a central and optional marshalling
+point for state detection (are we running in compile-time or run-time
+mode) and to act as a relatively light-weight module loader.
+
+=head2 Loaders and Forkers
+
+C<prefork> is intended to be used in two different ways.
+
+The first is by a module that wants to indicate that another module should
+be loaded before forking. This is known as a "Loader".
+
+The other is a script or module that will be initiating the forking. It
+will tell prefork.pm that it is either going to fork, or is about to fork,
+or for some other reason all modules previously mentioned by the Loaders
+should be loaded immediately.
+
+=head2 Usage as a Pragma
+
+A Loader can register a module to be loaded using the following
+
+  use prefork 'My::Module';
+
+The same thing can be done in such a way as to not require prefork
+being installed, but taking advantage of it if it is.
+
+  eval "use prefork 'My::Module';";
+
+A Forker can indicate that it will be forking with the following
+
+  use prefork ':enable';
+
+In any use of C<prefork> as a pragma, you can only pass a single value
+as argument. Any additional arguments will be ignored. (This may throw
+an error in future versions).
+
+=head2 Compatbility with mod_perl and others
+
+Part of the design of C<prefork>, and its minimalistic nature, is that it
+is intended to work easily with existing modules, needing only small
+changes.
+
+For example, C<prefork> itself will detect the C<$ENV{MOD_PERL}>
+environment variable and automatically start in forking mode.
+
+prefork has support for integrating with third-party modules, such as
+L<Class::Autouse>. The C<notify> function allows these run-time loaders
+to register callbacks, to be called once prefork enters forking mode.
+
+The synopsis entry above describes adding support for prefork.pm as a
+dependency. To allow your third-party module loader without a dependency
+and only if it is installed use the following:
+
+  eval { require prefork; }
+  prefork::notify( \&function ) unless $@;
+
+=head2 Using prefork.pm
+
+From the Loader side, it is fairly simple. prefork becomes a dependency
+for your module, and you use it as a pragma as documented above.
+
+For the Forker, you have two options. Use as a dependency or optional use.
+
+In the dependency case, you add prefork as a dependency and use it as a
+pragma with the ':enable' option.
+
+To add only optional support for prefork, without requiring it to be
+installed, you should wait until the moment just before you fork and then
+call C<prefork::enable> directly ONLY if it is loaded.
+
+  # Load modules if any use the prefork pragma.
+  prefork::enable() if $INC{prefork.pm};
+
+This will cause the modules to be loaded ONLY if there are any modules that
+need to be loaded. The main advantage of the dependency version is that you
+only need to enable the module once, and not before each fork.
+
+If you wish to have your own module leverage off the forking-detection that
+prefork provides, you can also do the following.

+  use prefork;
+  if ( $prefork::FORKING ) {

+=head2 enable
+
+The C<enable> function indicates to the prefork module that the process is
+going to fork, possibly immediately.
+
+When called, prefork.pm will immediately load all outstanding modules, and
+will set a flag so that any further 'prefork' calls will load the module
+at that time.
+
+Returns true, dieing as normal is there is a problem loading a module.

+
+=head2 notify &function
+
+The C<notify> function is used to integrate support for modules other than
+prefork.pm itself.
+
+A module loader calls the notify function, passing it a reference to a
+C<CODE> reference (either anon or a function reference). C<prefork> will
+store this CODE reference, and execute it immediately as soon as it knows
+it is in forking-mode, but after it loads its own modules.
+
+Callbacks are called in the order they are registered.
+
+Normally, this will happen as soon as the C<enable> function is called.
+
+However, you should be aware that if prefork is B<already> in preforking
+mode at the time that the notify function is called, prefork.pm will
+execute the function immediately.
+
+This means that any third party module loader should be fully loaded and
+initialised B<before> the callback is provided to C<notify>.
+
+Returns true if the function is stored, or dies if not passed a C<CODE>
+reference, or the callback is already set in the notify queue.
+
+=cut
+
+sub notify ($) {
+	# Get the CODE ref callback param
