NAME
       ExtUtils::MakeMaker::Tutorial - Writing a module with MakeMaker

SYNOPSIS
	   use ExtUtils::MakeMaker;

	   WriteMakefile(
	       NAME	       => 'Your::Module',
	       VERSION_FROM    => 'lib/Your/Module.pm'
	   );

DESCRIPTION
       This is a short tutorial on writing a simple module with MakeMaker.  It's really not that
       hard.

   The Mantra
       MakeMaker modules are installed using this simple mantra

	       perl Makefile.PL
	       make
	       make test
	       make install

       There are lots more commands and options, but the above will do it.

   The Layout
       The basic files in a module look something like this.

	       Makefile.PL
	       MANIFEST
	       lib/Your/Module.pm

       That's all that's strictly necessary.  There's additional files you might want:

	       lib/Your/Other/Module.pm
	       t/some_test.t
	       t/some_other_test.t
	       Changes
	       README
	       INSTALL
	       MANIFEST.SKIP
	       bin/some_program

       Makefile.PL
	   When you run Makefile.PL, it makes a Makefile.  That's the whole point of MakeMaker.
	   The Makefile.PL is a simple program which loads ExtUtils::MakeMaker and runs the
	   WriteMakefile() function to generate a Makefile.

	   Here's an example of what you need for a simple module:

	       use ExtUtils::MakeMaker;

	       WriteMakefile(
		   NAME 	   => 'Your::Module',
		   VERSION_FROM    => 'lib/Your/Module.pm'
	       );

	   NAME is the top-level namespace of your module.  VERSION_FROM is the file which
	   contains the $VERSION variable for the entire distribution.	Typically this is the
	   same as your top-level module.

       MANIFEST
	   A simple listing of all the files in your distribution.

		   Makefile.PL
		   MANIFEST
		   lib/Your/Module.pm

	   File paths in a MANIFEST always use Unix conventions (ie. /) even if you're not on
	   Unix.

	   You can write this by hand or generate it with 'make manifest'.

	   See ExtUtils::Manifest for more details.

       lib/
	   This is the directory where the .pm and .pod files you wish to have installed go.
	   They are laid out according to namespace.  So Foo::Bar is lib/Foo/Bar.pm.

       t/  Tests for your modules go here.  Each test filename ends with a .t.	So t/foo.t/
	   'make test' will run these tests.  The directory is flat, you cannot, for example,
	   have t/foo/bar.t run by 'make test'.

	   Tests are run from the top level of your distribution.  So inside a test you would
	   refer to ./lib to enter the lib directory, for example.

       Changes
	   A log of changes you've made to this module.  The layout is free-form.  Here's an
	   example:

	       1.01 Fri Apr 11 00:21:25 PDT 2003
		   - thing() does some stuff now
		   - fixed the wiggy bug in withit()

	       1.00 Mon Apr  7 00:57:15 PDT 2003
		   - "Rain of Frogs" now supported

       README
	   A short description of your module, what it does, why someone would use it and its
	   limitations.  CPAN automatically pulls your README file out of the archive and makes
	   it available to CPAN users, it is the first thing they will read to decide if your
	   module is right for them.

       INSTALL
	   Instructions on how to install your module along with any dependencies.  Suggested
	   information to include here:

	       any extra modules required for use
	       the minimum version of Perl required
	       if only works on certain operating systems

       MANIFEST.SKIP
	   A file full of regular expressions to exclude when using 'make manifest' to generate
	   the MANIFEST.  These regular expressions are checked against each file path found in
	   the distribution (so you're matching against "t/foo.t" not "foo.t").

	   Here's a sample:

	       ~$	   # ignore emacs and vim backup files
	       .bak$	   # ignore manual backups
	       \#	   # ignore CVS old revision files and emacs temp files

	   Since # can be used for comments, # must be escaped.

	   MakeMaker comes with a default MANIFEST.SKIP to avoid things like version control
	   directories and backup files.  Specifying your own will override this default.
