NAME
       Module::Build::Bundling - How to bundle Module::Build with a
       distribution

SYNOPSIS
         # Build.PL
         use inc::latest 'Module::Build';

         Module::Build->new(
           module_name => 'Foo::Bar',
           license => 'perl',
         )->create_build_script;

DESCRIPTION
       WARNING -- THIS IS AN EXPERIMENTAL FEATURE

       In order to install a distribution using Module::Build, users must have
       Module::Build available on their systems.  There are two ways to do
       this.  The first way is to include Module::Build in the
       "configure_requires" metadata field.  This field is supported by recent
       versions CPAN and CPANPLUS and is a standard feature in the Perl core
       as of Perl 5.10.1.  Module::Build now adds itself to
       "configure_requires" by default.

       The second way supports older Perls that have not upgraded CPAN or
       CPANPLUS and involves bundling an entire copy of Module::Build into the
       distribution's "inc/" directory.  This is the same approach used by
       Module::Install, a modern wrapper around ExtUtils::MakeMaker for
       Makefile.PL based distributions.

       The "trick" to making this work for Module::Build is making sure the
       highest version Module::Build is used, whether this is in "inc/" or
       already installed on the user's system.  This ensures that all
       necessary features are available as well as any new bug fixes.  This is
       done using the new inc::latest module.

       A "normal" Build.PL looks like this (with only the minimum required
       fields):

         use Module::Build;

         Module::Build->new(
           module_name => 'Foo::Bar',
           license     => 'perl',
         )->create_build_script;

       A "bundling" Build.PL replaces the initial "use" line with a nearly
       transparent replacement:

         use inc::latest 'Module::Build';

         Module::Build->new(
           module_name => 'Foo::Bar',
           license => 'perl',
         )->create_build_script;

       For authors, when "Build dist" is run, Module::Build will be
       automatically bundled into "inc" according to the rules for
       inc::latest.

       For users, inc::latest will load the latest Module::Build, whether
       installed or bundled in "inc/".

BUNDLING OTHER CONFIGURATION DEPENDENCIES
       The same approach works for other configuration dependencies -- modules
       that must be available for Build.PL to run.  All other dependencies can
       be specified as usual in the Build.PL and CPAN or CPANPLUS will install
       them after Build.PL finishes.

       For example, to bundle the Devel::AssertOS::Unix module (which ensures
       a "Unix-like" operating system), one could do this:

         use inc::latest 'Devel::AssertOS::Unix';
         use inc::latest 'Module::Build';

         Module::Build->new(
           module_name => 'Foo::Bar',
           license => 'perl',
         )->create_build_script;

       The "inc::latest" module creates bundled directories based on the
       packlist file of an installed distribution.  Even though "inc::latest"
       takes module name arguments, it is better to think of it as bundling
       and making available entire distributions.  When a module is loaded
       through "inc::latest", it looks in all bundled distributions in "inc/"
       for a newer module than can be found in the existing @INC array.

       Thus, the module-name provided should usually be the "top-level" module
       name of a distribution, though this is not strictly required.  For
       example, Module::Build has a number of heuristics to map module names
       to packlists, allowing users to do things like this:

         use inc::latest 'Devel::AssertOS::Unix';

       even though Devel::AssertOS::Unix is contained within the Devel-CheckOS
       distribution.

       At the current time, packlists are required.  Thus, bundling dual-core
       modules, including Module::Build, may require a 'forced install' over
       versions in the latest version of perl in order to create the necessary
       packlist for bundling.  This limitation will hopefully be addressed in
       a future version of Module::Build.

   WARNING -- How to Manage Dependency Chains
       Before bundling a distribution you must ensure that all prerequisites
       are also bundled and load in the correct order.  For Module::Build
       itself, this should not be necessary, but it is necessary for any other
       distribution.  (A future release of Module::Build will hopefully
       address this deficiency.)

       For example, if you need "Wibble", but "Wibble" depends on "Wobble",
       your Build.PL might look like this:

         use inc::latest 'Wobble';
         use inc::latest 'Wibble';
         use inc::latest 'Module::Build';

         Module::Build->new(
           module_name => 'Foo::Bar',
           license => 'perl',
         )->create_build_script;

       Authors are strongly suggested to limit the bundling of additional
       dependencies if at all possible and to carefully test their
       distribution tarballs on older versions of Perl before uploading to
       CPAN.
