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 + +=over 4 + +=item 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. + + +=item 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 L<ExtUtils::Manifest> for more details. + + +=item 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 F<lib/Foo/Bar.pm>. + + +=item t/ + +Tests for your modules go here. Each test filename ends with a .t. +So F<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. + + +=item 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 + + +=item 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. + + +=item 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 + + +=item 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. + + +=item bin/ + + +=back + +=head1 SEE ALSO + +L<perlmodstyle> gives stylistic help writing a module. + +L<perlnewmod> gives more information about how to write a module. + +There are modules to help you through the process of writing a module: +L<ExtUtils::ModuleMaker>, L<Module::Install>, L<PAR> + +=cut + +1; |
