=head1 NAME

Apache::TestMM - Provide MakeMaker Wrapper Methods

=head1 SYNOPSIS

  require Apache::TestMM;

  # import MY::test and MY::clean overrides for MM
  Apache::TestMM->import(qw(test clean));

  # parse command line args
  Apache::TestMM::filter_args();

  # autogenerate the script
  Apache::TestMM::generate_script('t/TEST');

=head1 DESCRIPTION

C<Apache::TestMM> provides wrappers for the C<ExtUtils::MakeMaker>
craft, making it easier to extend the autogenerated F<Makefile> with
C<Apache::Test>.

=head1 FUNCTIONS

=head2 C<import>

  use Apache::TestMM qw(test clean);

or:

  Apache::TestMM->import(qw(test clean));

Imports C<MY::> overrides for the default C<ExtUtils::MakeMaker>
I<test> and I<clean> targets, as if you have defined:

  sub MY::test {...}
  sub MY::clean {...}

in F<Makefile.PL>. C<Apache::TestMM> does this for you so that these Makefile
targets will run the Apache server and the tests for it, and clean up after
its mess.

=head2 C<filter_args>

  push @ARGV, '-apxs', $apxs_path;
  Apache::TestMM::filter_args();
  WriteMakefile(...);

When C<WriteMakefile()> is called it parses C<@ARGV>, hoping to find special
options like C<PREFIX=/home/stas/perl>. C<Apache::Test> accepts a lot of
options of its own. When C<Apache::TestMM::filter_args()> is called, it
removes any C<Apache::Test>-specific options from C<@ARGV> and stores them
internally, so when C<WriteMakefile()> is called they aren't in C<@ARGV> and
thus won't be processed by C<WriteMakefile()>.

The options can be set when F<Makefile.PL> is called:

  % perl Makefile.PL -apxs /path/to/apxs

Or you can push them manually to C<@ARGV> from the code:

  push @ARGV, '-apxs', $apxs_path;

When:

  Apache::TestMM::generate_script('t/TEST');

is called, C<Apache::Test>-specific options extracted by
C<Apache::TestMM::filter_args()> are written to the autogenerated
file. In our example, the autogenerated F<t/TEST> will include:

  %Apache::TestConfig::Argv = qw(apxs /path/to/apxs);

which is going to be used by the C<Apache::Test> runtime.

=head2 C<generate_script>

  Apache::TestMM::generate_script('t/TEST');

C<generate_script()> accepts the name of the script to generate and
will look for a template with the same name and suffix I<.PL>. So in
our example it'll look for F<t/TEST.PL>. The autogenerated script
F<t/TEST> will include the contents of F<t/TEST.PL>, and special
directives, including any configuration options passed via
C<L<filter_args()|/C_filter_args_>> called from F<Makefile.PL>, special
fixup code, etc. If no argument is passed to C<generate_script()>,
it will create a file named F<t/TEST> by default.
