NAME
    Apache::Bootstrap - Bootstraps dual life mod_perl1 and mod_perl2 Apache
    modules

SYNOPSIS
    In your Makefile.PL

     use Apache::Bootstrap 0.05;

     my $bootstrap;

     BEGIN {
        # make sure we have at least one minimum version required
        $bootstrap = Apache::Bootstrap->new({ mp2 => '1.99022', mp1 => 0, });
     }

     # write the Makefile using a mod_perl version dependent build subsystem
     $bootstrap->WriteMakefile( %maker_options );

     # check for Apache::Test, return the installed version if exists
     my $has_apache_test = $bootstrap->check_for_apache_test();

     # see if mod_perl2 is installed
     my $mp_generation = $bootstrap->satisfy_mp_generation( 2 );

     unless ($mp_generation) {

         # no mod_perl2?  look for mod_perl 1
         $mp_generation = $bootstrap->satisfy_mp_generation( 1 );
     }

     # any mod_perl version will do
     $mp_generation = Apache::Bootstrap->satisfy_mp_generation();
     unless ( $mp_generation ) {
          warn( 'No mod_perl installation was found' )
     } else {
          warn( "mod_perl generation $mp_generation was found" );
     }

METHODS
  new()
     # try to find these versions of mod_perl, die if none are found
     $bootstrap = Apache::Bootstrap->new({
         mod_perl2 => 1.99022, # after mp2 renaming
         mod_perl1 => 0,       # any verison of mp1
     });

  mp_prereqs()
     # returns the prerequisites for mod_perl versions in a hash reference

  check_for_apache_test()
     $apache_test_version = Apache::Bootstrap->check_for_apache_test;

    Returns the version of Apache::Test installed. Returns undefined if
    Apache::Test is not installed.

  satisfy_mp_generation()
     # see if mod_perl2 is installed
     my $mp_generation = Apache::Bootstrap->satisfy_mp_generation( 2 );

     unless ($mp_generation) {

         # no mod_perl2?  look for mod_perl 1
         $mp_generation = Apache::Bootstrap->satisfy_mp_generation( 1 );
     }

     # any mod_perl version will do
     $mp_generation = Apache::Bootstrap->satisfy_mp_generation();
     unless ( $mp_generation ) {
         warn( 'No mod_perl installation was found' )
     } else {
         warn( "mod_perl generation $mp_generation was found" );
     }

    Currently the logic for determining the mod_perl generation is as
    follows.

     # If a specific generation was passed as an argument,
     #     if satisfied
     #         return the same generation
     #     else
     #         die
     # else @ARGV and %ENV will be checked for specific orders
     #     if the specification will be found
     #         if satisfied
     #             return the specified generation
     #         else
     #             die
     #     else if any mp generation is found
     #              return it
     #           else
     #              die

  apache_major_version()
     $apache_major_version = $bootstrap->apache_major_version;

    The major version number of the target apache install

  WriteMakefile()
     $bootstrap->write_makefile( %makefile_options );

    Writes the makefile using the appropriate make engine depending on what
    mod_perl version is in use. Same API as ExtUtils::MakeMaker or
    ModPerl::BuildMM
