Installing Modules
When you want to install a module that you don’t already have, sometimes you can
simply download the distribution, unpack it, and run a series of commands from the
shell. Check for a README or INSTALL file that gives you more information. If the
module uses MakeMaker,† the sequence will be something like this:
$ perl Makefile.PL
$ make install
