NAME
    CPAN::Porters - resource for people maintaining packages of CPAN modules
    in various distributions

SYNOPSIS
    CPAN modules can be either installed from source (downloaded directly
    from CPAN) or they can be installed with the package mangement system of
    your distribution.

    CPAN::Porters is a resource for people who are maintaining those
    packages in the various distributions.

Reasoning
    When developing an application we usually don't want to build our own
    machine. Neither compile our own kernel. In most of the cases we won't
    want to compile and install our own version of a database engine nor
    Apache or any other 3rd party tool. So my assumption is that we won't
    want to install our CPAN dependencies either. Again - in the standard
    case.

    For people just using an application written in Perl it is even more
    important that they should not deal with all these packages. Most of us
    know how much people suffer when they need to install 10s of modules and
    their dependencies from CPAN. Especially for modules with dependencies
    outside of CPAN.

    While CPAN.pm, CPANPLUS.pm have improved a lot they still cannot deal
    with cases when one of the dependencies fails to install cleanly.

    In addition while we usually want to work with recent versions of
    modules from CPAN, we usually don't want to get the bleeding edge.
    Espcially not in applications.

Guidelines for inclusion
    In addition to the guidelines of each distribution on which module to
    include, when to upgrade etc. we would like to setup our own guidelines
    to help people decide what to include, what would be the priorites, when
    to upgrade a module etc.

    A few guidelines on how to select and prioritize modules:

    * Modules that are dependencies of another module by a different module
    author.
    * Modules that require compilation
    * Modules that require files not on CPAN
        Such modules are especially difficult to install with CPAN.pm or
        CPANPLUS as they require files outside the scope of CPAN. Making
        sure such modules and their dependencies can be installed with the
        standard packaging system gets extra points.

    * Web development frameworks
    * Modules required by some of the big open source Perl applications.
             For a good listing see the journal entry of brian d foy
             L<http://use.perl.org/~brian_d_foy/journal/9974>

    Requirements for inclusion or upgrade

    * The module already has all its prereq in the system
    * The module passes all its tests with its prereqs currently in the
    system on the system
    * The tests of all the currently available dependent modules in the
    system pass with this new version
    * A broader requirement would be that the version has no failing test
    reports on any other system, though this requirement might be too harsh
    and unnecessary
Guidelines for module authors
    In order to make packaging of CPAN modules for the various distros
    easier module authors should create and package their module adhering to
    some standards. Following is a wishlist created by the Debian Perl
    module maintainers:
    <http://people.debian.org/~terpstra/message/20080304.104744.f5ca7c1c.en.
    html>

    * Sane version numbering
        While having the version in a uniform way might be nice, it would be
        already helpful if one module used a consistent scheme.

        That is stick try to stick to the whatever version numbering scheme
        you have started.

        "We have way too many modules where we have to do
        {d,u}versionmangling because they switch from x.yyyy to x.yy and
        x.yy.zz or stuff like that (and we try to add 00$ or strip it or
        divide .xxxx into .xx.yy or something like that)."

        TODO: list a few reasonable scheme here:

         \d+\.\d\d(_\d\d)?

    * Copyrights/licensing
        Ideally each and every file in given CPAN distribution should have
        clearly stated copyright and license information. AUTHORS/CHANGES
        (if properly filled) can be used as a source of guessing, but I
        think guessing about legal stuff is nothing we want daily.

    * No interactive prompting during installation
        No interactive prompting from Makefile.PL or other parts of the
        build system without corresponding (and documented!) ways of setting
        the same parameters automatically.

    * No network access during build
        no network access needed for building and testing (or an easy and
        documented way to turn network tests off).

    * Use standar packaging systems
        Please use one of the standard Perl module build packages if at all
        possible. (This probably goes without saying.)

    * Structured POD
        POD documentation for modules should be structured as described in
        the pod2man man page. In particular, the NAME section and its
        content is mandatory. Otherwise, one doesn't get a valid man page.

        Make sure your POD documentation makes sense when translated with
        pod2man. I went several times, i.e., over all of PDF::API2's
        manpages because they used "=head1 PDF::API2::Some::Thing" instead
        of "=head1 NAME". Those bugs take a _lot_ of time to properly patch!

        POD is not just to be used by perldoc.

    * Don't ship Makefiles
        Please don't ship generated Makefiles etc.

    * Testing
        Don't use conditions in tests that test for the existence of author
        specfic files or settings (" unless -d '.svn'" or "unless $username
        eq 'timbo'")

        Specifically, don't do this unless that's being used as a criteria
        for skipping a test that's really meaningless outside of the
        author's environment. (I do have a few tests in modules that depend
        on local infrastructure to run and hence are skipped if they're not
        run by me.)

Distributions
    For our purposes a distribution is one if the Linux (or BSD)
    distributions with its own rpm or deb (...) based packaging system. It
    can also be some stand-alone Perl package such as the ActivePerl of
    ActiveState or Vanilla and Strawberry Perl.

  Ubuntu
    My current understanding is that the best way to get CPAN modules into
    Ubuntu is to get them into Debian unstable and then sync them into
    Ubuntu universe.

    Look at Gutsy Gibson (7.10) development forum
    <http://ubuntuforums.org/forumdisplay.php?f=238> and more specifically
    at Requesting New Packages for Inclusion in Gutsy Universe
    <http://ubuntuforums.org/showthread.php?t=414355>

  Fedora
    More details needed.

    For now look at <http://fedoraproject.org/> and

    <http://fedoraproject.org/wiki/SIGs/Perl?action=show&redirect=Perl>

    <http://www.redhat.com/mailman/listinfo/fedora-perl-devel-list>

    And the wish-list so far:

    * Clearly and properly copyright your works.
    * Always apply a widely used and commonly acknowledged license to your
    works.
