SYNOPSIS
        # Initialize
        perlbrew init

        # Install some Perls
        perlbrew install perl-5.12.1
        perlbrew install perl-5.8.1
        perlbrew install perl-5.11.5

        # See what were installed
        perlbrew installed

        # Switch perl in the $PATH
        perlbrew switch perl-5.12.1
        perl -v

        # Switch to another version
        perlbrew switch perl-5.8.1
        perl -v

        # Switch to a certain perl executable not managed by perlbrew.
        perlbrew switch /usr/bin/perl

        # Or turn it off completely. Useful when you messed up too deep.
        perlbrew off

        # Use 'switch' command to turn it back on.
        perlbrew switch perl-5.12.1

DESCRIPTION
    perlbrew is a program to automate the building and installation of perl
    in the users HOME. At the moment, it installs everything to
    "~/perl5/perlbrew", and requires you to tweak your PATH by including a
    bashrc/cshrc file it provides. You then can benefit from not having to
    run 'sudo' commands to install cpan modules because those are installed
    inside your HOME too. It's almost like an isolated perl environments.

INSTALLATION
    The recommended way to install perlbrew is to run these statements in
    your shell:

        curl -LO http://xrl.us/perlbrew
        chmod +x perlbrew
        ./perlbrew install

    After that, "perlbrew" installs itself to "~/perl5/perlbrew/bin", and
    you should follow the instruction on screen to setup your ".bashrc" or
    ".cshrc" to put it in your PATH.

    The directory "~/perl5/perlbrew" will contain all install perl
    executables, libraries, documentations, lib, site_libs. If you need to
    install "perlbrew", and the perls it brews, into somewhere else because,
    say, your HOME has limited quota, you can do that by setting a
    "PERLBREW_ROOT" environment variable before you run "./perlbrew
    install".

        export PERLBREW_ROOT=/mnt/perlbrew
        ./perlbrew install

    The downloaded perlbrew is a self-contained standalone program that
    embed all non-core modules it uses. It should be runnable with perl 5.8
    or high versions of perls.

    You may also install perlbrew from CPAN with cpan / cpanp / cpanm:

        cpan App::perlbrew

    This installs 'perlbrew' into your current PATH and it is always
    executed with your current perl.

    NOTICE. When you install or upgrade perlbrew with cpan / cpanp / cpanm,
    make sure you are not using one of the perls brewed with perlbrew. If
    so, the `perlbrew` executable you just installed will not be available
    after you swith to other perls. You might not be able to invoke further
    "perlbrew" commands after so because the executable "perlbrew" is not in
    your "PATH" anymore. Installing it again with cpan can temporarily
    solved this problem.

    It should be relatively safe to install "App::perlbrew" with system cpan
    (like "/usr/bin/cpan") because then it will be installed under a system
    PATH like "/usr/bin", which is not effected by "perlbrew switch"
    command.

    Again, it is recommended to let "perlbrew" install itself. It's easier,
    and it works better.

USAGE
    Please read the program usage by running

        perlbrew

    (No arguments.) To read a more detail one:

        perlbrew -h

    Alternatively, this should also do:

        perldoc perlbrew

    If you messed up to much or get confused by having to many perls
    installed, you can do:

        perlbrew switch /usr/bin/perl

    It will make sure that your current perl in the PATH is pointing to
    "/usr/bin/perl".

    As a matter of fact the "switch" command checks whether the given
    argument is an executale or not, and create a symlink named 'perl' to it
    if it is. If you really want to you are able to do:

        perlbrew switch /usr/bin/perl6

    But maybe not. After running this you might not be able to run perlbrew
    anymore. So be careful not making mistakes there.
