-=head1 NAME
-
-ExtUtils::Embed - Utilities for embedding Perl in C/C++ applications
-
-=head1 SYNOPSIS
-
-
- perl -MExtUtils::Embed -e xsinit
- perl -MExtUtils::Embed -e ldopts
-
-=head1 DESCRIPTION
-
-ExtUtils::Embed provides utility functions for embedding a Perl interpreter
-and extensions in your C/C++ applications.
-Typically, an application B<Makefile> will invoke ExtUtils::Embed
-functions while building your application.
-
-=head1 @EXPORT
-
-ExtUtils::Embed exports the following functions:
-
-L<xsinit()>, L<ldopts()>, L<ccopts()>, L<perl_inc()>, L<ccflags()>,
-L<ccdlflags()>, L<xsi_header()>, L<xsi_protos()>, L<xsi_body()>
-
-=head1 FUNCTIONS
-
-=item xsinit()
-
-Generate C/C++ code for the XS intializer function.
-
-When invoked as C<`perl -MExtUtils::Embed -e xsinit --`>
-the following options are recognized:
-
-B<-o> <output filename> (Defaults to B<perlxsi.c>)
-
-B<-o STDOUT> will print to STDOUT.
-
-B<-std> (Write code for extensions that are linked with the current Perl.)
-
-Any additional arguments are expected to be names of modules
-to generate code for.
-
-When invoked with parameters the following are accepted and optional:
-
-C<xsinit($filename,$std,[@modules])>
-
-Where,
-
-B<$filename> is equivalent to the B<-o> option.
-
-B<$std> is boolean, equivalent to the B<-std> option.
-
-B<[@modules]> is an array ref, same as additional arguments mentioned above.
-
-=item Examples
-
-
- perl -MExtUtils::Embed -e xsinit -- -o xsinit.c Socket
-
-
-This will generate code with an B<xs_init> function that glues the perl B<Socket::bootstrap> function
-to the C B<boot_Socket> function and writes it to a file named "xsinit.c".
-
-Note that B<DynaLoader> is a special case where it must call B<boot_DynaLoader> directly.
-
- perl -MExtUtils::Embed -e xsinit
-
-
-This will generate code for linking with B<DynaLoader> and
-each static extension found in B<$Config{static_ext}>.
-The code is written to the default file name B<perlxsi.c>.
-
-
- perl -MExtUtils::Embed -e xsinit -- -o xsinit.c -std DBI DBD::Oracle
-
-
-Here, code is written for all the currently linked extensions along with code
-for B<DBI> and B<DBD::Oracle>.
-
-If you have a working B<DynaLoader> then there is rarely any need to statically link in any
-other extensions.
-
-=item ldopts()
-
-Output arguments for linking the Perl library and extensions to your
-application.
-
-When invoked as C<`perl -MExtUtils::Embed -e ldopts --`>
-the following options are recognized:
-
-B<-std>
-
-Output arguments for linking the Perl library and any extensions linked
-with the current Perl.
-
-B<-I> <path1:path2>
-
-Search path for ModuleName.a archives.
-Default path is B<@INC>.
-Library archives are expected to be found as
-B</some/path/auto/ModuleName/ModuleName.a>
-For example, when looking for B<Socket.a> relative to a search path,
-we should find B<auto/Socket/Socket.a>
-
-When looking for B<DBD::Oracle> relative to a search path,
-we should find B<auto/DBD/Oracle/Oracle.a>
-
-Keep in mind, you can always supply B</my/own/path/ModuleName.a>
-as an additional linker argument.
-
-B<--> <list of linker args>
-
-Additional linker arguments to be considered.
-
-Any additional arguments found before the B<--> token
-are expected to be names of modules to generate code for.
-
-When invoked with parameters the following are accepted and optional:
-
-C<ldopts($std,[@modules],[@link_args],$path)>
-
-Where,
-
-B<$std> is boolean, equivalent to the B<-std> option.
-
-B<[@modules]> is equivalent to additional arguments found before the B<--> token.
-
-B<[@link_args]> is equivalent to arguments found after the B<--> token.
-
-B<$path> is equivalent to the B<-I> option.
-
-In addition, when ldopts is called with parameters, it will return the argument string
-rather than print it to STDOUT.
-
-=item Examples
-
-
- perl -MExtUtils::Embed -e ldopts
-
-
-This will print arguments for linking with B<libperl.a>, B<DynaLoader> and
-extensions found in B<$Config{static_ext}>. This includes libraries
-found in B<$Config{libs}> and the first ModuleName.a library
-for each extension that is found by searching B<@INC> or the path
-specifed by the B<-I> option.
-In addition, when ModuleName.a is found, additional linker arguments
-are picked up from the B<extralibs.ld> file in the same directory.
-
-
- perl -MExtUtils::Embed -e ldopts -- -std Socket
-
-
-This will do the same as the above example, along with printing additional arguments for linking with the B<Socket> extension.
-
-
- perl -MExtUtils::Embed -e ldopts -- DynaLoader
-
-
-This will print arguments for linking with just the B<DynaLoader> extension
-and B<libperl.a>.
-
-
- perl -MExtUtils::Embed -e ldopts -- -std Msql -- -L/usr/msql/lib -lmsql
-
-
-Any arguments after the second '--' token are additional linker
-arguments that will be examined for potential conflict. If there is no
-conflict, the additional arguments will be part of the output.
-
-
-=item perl_inc()
-
-For including perl header files this function simply prints:
-
- -I $Config{archlib}/CORE
-
-So, rather than having to say:
-
- perl -MConfig -e 'print "-I $Config{archlib}/CORE"'
-
-Just say:
-
- perl -MExtUtils::Embed -e perl_inc
-
-=item ccflags(), ccdlflags()
-
-These functions simply print $Config{ccflags} and $Config{ccdlflags}
-
-=item ccopts()
-
-This function combines perl_inc(), ccflags() and ccdlflags() into one.
-
-=item xsi_header()
-
-This function simply returns a string defining the same B<EXTERN_C> macro as
-B<perlmain.c> along with #including B<perl.h> and B<EXTERN.h>.
-
-=item xsi_protos(@modules)
-
-This function returns a string of B<boot_$ModuleName> prototypes for each @modules.
-
-=item xsi_body(@modules)
-
-This function returns a string of calls to B<newXS()> that glue the module B<bootstrap>
-function to B<boot_ModuleName> for each @modules.
-
-B<xsinit()> uses the xsi_* functions to generate most of it's code.
