           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.
