From [1]:

    cpanminus (cpanm) is an attempt to make a zero-configuration client
    that automatically does the right thing for most users. It's also
    designed to run well on systems with limited resources (e.g. a VPS).
    It doesn't come with Perl, but it's easy to install.
    It integrates easily with local::lib.
