NAME
    perlrocks - CPAN installation management

VERSION
    0.02

SYNOPSIS
    A command 'perlrocks' is installed to install cpan distributions:

        > perlrocks search Moose

        # Install multiple vesion of Moose
        > perlrocks install -v 2.0009 Moose
        > perlrocks install -v 1.13 Moose

        # Uninstall is possible
        > rock uninstall Moose-1.14

    Modify your program a little bit to make it effective.

        # Put this in the very beginning of your program.
        use perlrocks;

        # Using the latest version of intsalled Moose
        use Moose;

        # Using exactly the version 2.0008 of Moose.
        use Moose-2.0008

DESCRIPTION
    This `perlrocks` things provides a mechanism to install multiple
    versions of CPAN distributions, and use specific one in programs.

    In Perl5, the statement "use Foo 1.0" or "use Foo-1.0" means to load
    Foo.pm and check if $Foo::VERSION is at least 1.0. perlrocks alters that
    behavior to load exactly Foo 1.0. If only higher versions of Foo are
    found, it dies.

    In order to do that, `perlrocks` makes perl search libs in a different
    way. Therefore, you need to install CPAN distributions differently. To
    do so, you must use the "perlrocks" command:

        perlrocks install -v 2.0008 Moose
        perlrocks install -v 2.0009 Moose

    Also notice here in the document, the term "distribution" is used to
    refer to "the thing that gets uploaded to CPAN". Not "module", not
    "package". For example, To install MooseX::Struct module, you'll need to
    figure out the distribution name that provides it, in this case it's
    "MooseX-Struct":

        perlrocks install MooseX-Struct

    Since one CPAN distribution can contain as many modules as needed, each
    with different versions, it is ambiguous to state the command to install
    "Foo::Bar" module, with the version number refering to the "Foo"
    distribution.

    Be aware of that "perlrocks.pm" tweaks your %INC, and it maybe
    significantly slower. Use it at your own risk.
