+Perl modules are distributed via CPAN, and there is the official, standard CPAN
+client, simply called +cpan+. It comes with every Perl installation and can be
+used to install the testsuite. Many users prefer to use the more modern
++cpanminus+ instead, though (because it asks no questions and just works):
