             ...

Description

       "ModPerl::MM" is a "subclass" of "ExtUtils::MakeMaker" for mod_perl 2.0, to a degree of sub-classability
       of "ExtUtils::MakeMaker".

       When ModPerl::MM::WriteMakefile() is used instead of ExtUtils::MakeMaker::WriteMakefile(), "ModPerl::MM"
       overrides several "ExtUtils::MakeMaker" methods behind the scenes and supplies default WriteMakefile()
       arguments adjusted for mod_perl 2.0 build. It's written in such a way so that normally 3rd party module
       developers for mod_perl 2.0, don't need to mess with Makefile.PL at all.

MY::" Default Methods

       "ModPerl::MM" overrides method foo as long as Makefile.PL hasn't already specified a method MY::foo. If
       the latter happens, "ModPerl::MM" will DWIM and do nothing.

       In case the functionality of "ModPerl::MM" methods needs to be extended, rather than completely
       overridden, the "ModPerl::MM" methods can be called internally. For example if you need to modify
       constants in addition to the modifications applied by "ModPerl::MM::MY::constants", call the
       "ModPerl::MM::MY::constants" method (notice that it resides in the package "ModPerl::MM::MY" and not
       "ModPerl::MM"), then do your extra manipulations on constants:

         # if there is a need to extend the methods
         sub MY::constants {
             my $self = shift;
             $self->ModPerl::MM::MY::constants;
             # do something else;
         }

       In certain cases a developers may want to prevent from "ModPerl::MM" to override certain methods. In that
       case an explicit override in Makefile.PL will do the job. For example if you don't want the constants()
       method to be overridden by "ModPerl::MM", add to your Makefile.PL:

         sub MY::constants { shift->MM::constants(@_); }";

       "ModPerl::MM" overrides the following methods:

   "ModPerl::MM::MY::post_initialize"
       This method is deprecated.

WriteMakefile() Default Arguments

       "ModPerl::MM::WriteMakefile" supplies default arguments such as "INC" and "TYPEMAPS" unless they weren't
       passed to "ModPerl::MM::WriteMakefile" from Makefile.PL.

       If the default values aren't satisfying these should be overridden in Makefile.PL. For example to supply
       an empty INC, explicitly set the argument in Makefile.PL.

         ModPerl::MM::WriteMakefile(
             ...
             INC => '',
             ...
         );

       If instead of fully overriding the default arguments, you want to extend or modify them, they can be
       retrieved using the ModPerl::MM::get_def_opt() function. The following example appends an extra value to
       the default "INC" attribute:

         my $extra_inc = "/foo/include";
         ModPerl::MM::WriteMakefile(
             ...
             INC => join " ", $extra_inc, ModPerl::MM::get_def_opt('INC'),
             ...
         );

       "ModPerl::MM" supplies default values for the following "ModPerl::MM::WriteMakefile" attributes:

   "CCFLAGS"
   "LIBS"
   "INC"
   "OPTIMIZE"
   "LDDLFLAGS"
   "TYPEMAPS"
   "dynamic_lib"
       "OTHERLDFLAGS"

         dynamic_lib => { OTHERLDFLAGS => ... }

   "macro"
       "MOD_INSTALL"

         macro => { MOD_INSTALL => ... }

       makes sure that Apache-Test/ is added to @INC.
