           # Or want to go back to the system Perl.
           perlbrew off

           # Use 'switch' command to turn it back on.
           perlbrew switch perl-5.12.2

           perlbrew exec -- perl -E 'say $]'

DESCRIPTION

       perlbrew is a program to automate the building and installation of perl in an easy way. 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 provides multiple isolated perl environments, and a
       mechanism for you to switch between them.

       For the documentation of perlbrew usage see perlbrew command on CPAN, or by running "perlbrew help". The
       following documentation features the API of "App::perlbrew" module, and may not be remotely close to what
       your want to read.

INSTALLATION

       It is the simplest to use the perlbrew installer, just paste this statement to your terminal:

           curl -kL http://install.perlbrew.pl | bash

       Or this one, if you have "fetch" (default on FreeBSD):

           fetch -o- http://install.perlbrew.pl | sh

       After that, "perlbrew" installs itself to "~/perl5/perlbrew/bin", and you should follow the instruction
       on screen to modify your shell rc file to put it in your PATH.

       The installed perlbrew command is a standalone executable that can be run with system perl. The minimum
       system perl version requirement is 5.8.0, which should be good enough for most of the OSes these days.

       A packed version of "patchperl" to "~/perl5/perlbrew/bin", which is required to build old perls.

       The directory "~/perl5/perlbrew" will contain all install perl executables, libraries, documentations,
       lib, site_libs. In the documentation, that directory is referred as "perlbrew root". If you need to set
       it to somewhere else because, say, your HOME has limited quota, you can do that by setting
       "PERLBREW_ROOT" environment variable before running the installer:

           export PERLBREW_ROOT=/opt/perl5
           curl -kL http://install.perlbrew.pl | bash

       You may also install perlbrew from CPAN:

           cpan App::perlbrew

       In this case, the perlbrew command is installed as "/usr/bin/perlbrew" or "/usr/local/bin/perlbrew" or
       others, depending on the location of your system perl installation.

       Please make sure not to run this with one of the perls brewed with perlbrew. It's the best to turn
       perlbrew off before you run that, if you're upgrading.

           perlbrew off
           cpan App::perlbrew

       You should always use system cpan (like /usr/bin/cpan) to install "App::perlbrew" because it will be
       installed under a system PATH like "/usr/bin", which is not affected by perlbrew "switch" or "use"
       command.

       The "self-upgrade" command will not upgrade the perlbrew installed by cpan command, but it is also easy
       to upgrade perlbrew by running `cpan App::perlbrew` again.

METHODS

       (Str) current_perl
           Return the "current perl" object attribute string, or, if absent, the value of PERLBREW_PERL
           environment variable.

       (Str) current_perl (Str)
           Set the "current_perl" object attribute to the given value.
