Devel::PatchPerl - Patch perl source a la Devel::PPPort's buildperl.pl

       Chris Williams <chris@bingosnet.co.uk>

       Devel::PatchPerl is intended only to facilitate the "building" of perls, not to facilitate the  "testing"
       of perls. This means that it will not patch failing tests in the perl testsuite.

       Devel::PatchPerl is a modularisation of the patching code contained in Devel::PPPort's "buildperl.pl".

       It does not build perls, it merely provides an interface to the source patching functionality.

       "patch_source"
           Takes  two  parameters,  a "perl" version and the path to unwrapped perl source for that version.  It
           dies on any errors.

           If you don't supply a "perl" version, it will attempt to auto-determine the "perl" version  from  the
           specified path.

           If you don't supply the path to unwrapped perl source, it will assume the current working directory.

       "determine_version"
           Takes  one  optional parameter, the path to unwrapped perl source. It returns the perl version of the
           source code at the given location. It returns undef on error.

           If you don't supply the path to unwrapped perl source, it will assume the current working directory.

       Devel::PatchPerl will normally update the "patchlevel.h" file in the perl source tree to indicate that it
       has applied local patches. This behaviour is negated if it is detected that it  is  operating  in  a  git
       repository.  To  override  this  and  update  "patchlevel.h"  when  in  a Git repository, set the env var
       "PERL5_PATCHPERL_PATCHLEVEL" to a true value.

       Alternatively, call "patchperl" with the "--patchlevel" option.
