.SH "Description"
.IX Header "Description"
\&\f(CW\*(C`ModPerl::MM\*(C'\fR is a \*(L"subclass\*(R" of \f(CW\*(C`ExtUtils::MakeMaker\*(C'\fR for mod_perl
2.0, to a degree of sub-classability of \f(CW\*(C`ExtUtils::MakeMaker\*(C'\fR.
.PP
When \f(CW\*(C`ModPerl::MM::WriteMakefile()\*(C'\fR is used instead of
\&\f(CW\*(C`ExtUtils::MakeMaker::WriteMakefile()\*(C'\fR, \f(CW\*(C`ModPerl::MM\*(C'\fR overrides
several \f(CW\*(C`ExtUtils::MakeMaker\*(C'\fR methods behind the scenes and supplies
default \f(CW\*(C`WriteMakefile()\*(C'\fR 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 \fIMakefile.PL\fR at
all.
.ie n .SH """MY::"" Default Methods"
.el .SH "\f(CWMY::\fP Default Methods"
.IX Header "MY:: Default Methods"
\&\f(CW\*(C`ModPerl::MM\*(C'\fR overrides method \fIfoo\fR as long as \fIMakefile.PL\fR
hasn't already specified a method \fIMY::foo\fR. If the latter happens,
\&\f(CW\*(C`ModPerl::MM\*(C'\fR will \s-1DWIM\s0 and do nothing.
.PP
In case the functionality of \f(CW\*(C`ModPerl::MM\*(C'\fR methods needs to be
extended, rather than completely overridden, the \f(CW\*(C`ModPerl::MM\*(C'\fR methods
can be called internally. For example if you need to modify constants
in addition to the modifications applied by
\&\f(CW\*(C`ModPerl::MM::MY::constants\*(C'\fR, call the \f(CW\*(C`ModPerl::MM::MY::constants\*(C'\fR
method (notice that it resides in the package \f(CW\*(C`ModPerl::MM::MY\*(C'\fR and
not \f(CW\*(C`ModPerl::MM\*(C'\fR), then do your extra manipulations on constants:
.PP
.Vb 6
\&  # if there is a need to extend the methods 
\&  sub MY::constants {
\&      my $self = shift;
\&      $self\->ModPerl::MM::MY::constants;
\&      # do something else;
\&  }
.Ve
.PP
In certain cases a developers may want to prevent from \f(CW\*(C`ModPerl::MM\*(C'\fR
to override certain methods. In that case an explicit override in
\&\fIMakefile.PL\fR will do the job. For example if you don't want the
\&\f(CW\*(C`constants()\*(C'\fR method to be overridden by \f(CW\*(C`ModPerl::MM\*(C'\fR, add to your
\&\fIMakefile.PL\fR:
.PP
.Vb 1
\&  sub MY::constants { shift\->MM::constants(@_); }";
.Ve
.PP
\&\f(CW\*(C`ModPerl::MM\*(C'\fR overrides the following methods:
.ie n .SS """ModPerl::MM::MY::post_initialize"""
.el .SS "\f(CWModPerl::MM::MY::post_initialize\fP"
.IX Subsection "ModPerl::MM::MY::post_initialize"
This method is deprecated.
.ie n .SH """WriteMakefile()"" Default Arguments"
.el .SH "\f(CWWriteMakefile()\fP Default Arguments"
.IX Header "WriteMakefile() Default Arguments"
\&\f(CW\*(C`ModPerl::MM::WriteMakefile\*(C'\fR supplies default arguments such as
\&\f(CW\*(C`INC\*(C'\fR and \f(CW\*(C`TYPEMAPS\*(C'\fR unless they weren't passed to
\&\f(CW\*(C`ModPerl::MM::WriteMakefile\*(C'\fR from \fIMakefile.PL\fR.
.PP
If the default values aren't satisfying these should be overridden in
\&\fIMakefile.PL\fR. For example to supply an empty \s-1INC,\s0 explicitly set the
argument in \fIMakefile.PL\fR.
.PP
.Vb 5
\&  ModPerl::MM::WriteMakefile(
\&      ...
\&      INC => \*(Aq\*(Aq,
\&      ...
\&  );
.Ve
.PP
If instead of fully overriding the default arguments, you want to
extend or modify them, they can be retrieved using the
\&\f(CW\*(C`ModPerl::MM::get_def_opt()\*(C'\fR function. The following example appends
an extra value to the default \f(CW\*(C`INC\*(C'\fR attribute:
.PP
.Vb 6
\&  my $extra_inc = "/foo/include";
\&  ModPerl::MM::WriteMakefile(
\&      ...
\&      INC => join " ", $extra_inc, ModPerl::MM::get_def_opt(\*(AqINC\*(Aq),
\&      ...
\&  );
.Ve
