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.  Its 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 Make-
           Maker.  The Makefile.PL is a simple module which loads ExtUtils::MakeMaker and
           runs the WriteMakefile() function with a few simple arguments.

           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

           Filepaths 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’.

       lib/
           This is the directory where your .pm and .pod files you wish to have installed
           go.  They are layed 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.  Sug-
           gested 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
           filepath 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 con-
           trol directories and backup files.  Specifying your own will override this
           default.
