“What’s CPAN Minus (or ‘cpanm’ if you prefer the caps-challenged
version) for? Installing CPAN modules, period. It can get, unpack,
build, and install Perl modules from CPAN — but it can’t do any of
the other stuff the CPAN shell can do. It’s meant to require zero
configuration, and it runs as a standalone application.
“You can get cpanm a couple of ways — some distros may already
package it. If not, you can follow the installation instructions or
grab it from Github and install it that way.”
