.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
When creating a \f(CW\*(C`Build.PL\*(C'\fR script for a module, something like the
following code will typically be used:
.PP
.Vb 12
\&  use Module::Build;
\&  my $build = Module::Build\->new
\&    (
\&     module_name => \*(AqFoo::Bar\*(Aq,
\&     license  => \*(Aqperl\*(Aq,
\&     requires => {
\&                  \*(Aqperl\*(Aq          => \*(Aq5.6.1\*(Aq,
\&                  \*(AqSome::Module\*(Aq  => \*(Aq1.23\*(Aq,
\&                  \*(AqOther::Module\*(Aq => \*(Aq>= 1.2, != 1.5, < 2.0\*(Aq,
\&                 },
\&    );
\&  $build\->create_build_script;
.Ve
.PP
A simple module could get away with something as short as this for its
\&\f(CW\*(C`Build.PL\*(C'\fR script:
.PP
.Vb 5
\&  use Module::Build;
\&  Module::Build\->new(
\&    module_name => \*(AqFoo::Bar\*(Aq,
\&    license     => \*(Aqperl\*(Aq,
\&  )\->create_build_script;
.Ve
.PP
The model used by \f(CW\*(C`Module::Build\*(C'\fR is a lot like the \f(CW\*(C`MakeMaker\*(C'\fR
metaphor, with the following correspondences:
.PP
.Vb 5
\&   In Module::Build                 In ExtUtils::MakeMaker
\&  \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-      \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-
\&   Build.PL (initial script)        Makefile.PL (initial script)
\&   Build (a short perl script)      Makefile (a long Makefile)
\&   _build/ (saved state info)       various config text in the Makefile
.Ve
.PP
Any customization can be done simply by subclassing \f(CW\*(C`Module::Build\*(C'\fR
and adding a method called (for example) \f(CW\*(C`ACTION_test\*(C'\fR, overriding
the default 'test' action.  You could also add a method called
\&\f(CW\*(C`ACTION_whatever\*(C'\fR, and then you could perform the action \f(CW\*(C`Build
whatever\*(C'\fR.
.PP
For information on providing compatibility with
\&\f(CW\*(C`ExtUtils::MakeMaker\*(C'\fR, see Module::Build::Compat and
<http://www.makemaker.org/wiki/index.cgi?ModuleBuildConversionGuide>.
.SH "STRUCTURE"
.IX Header "STRUCTURE"
Module::Build creates a class hierarchy conducive to customization.
Here is the parent-child class hierarchy in classy \s-1ASCII\s0 art:
.PP
.Vb 10
\&   /\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\e
\&   |   Your::Parent     |  (If you subclass Module::Build)
\&   \e\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-/
\&            |
\&            |
\&   /\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\e  (Doesn\*(Aqt define any functionality

\&            |
\&            |
\&   /\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\e  (Some values of $^O may

\&            |
\&   /\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\e
\&   |   Module::Build::Base    |  (Most of the functionality of 
\&   \e\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-/   Module::Build is defined here.)
.Ve
.SH "SUBCLASSING"
.IX Header "SUBCLASSING"
Right now, there are two ways to subclass Module::Build.  The first
way is to create a regular module (in a \f(CW\*(C`.pm\*(C'\fR file) that inherits
from Module::Build, and use that module's class instead of using
Module::Build directly:
