=head1 NAME

critic.t - a unit test from Test::Perl::Critic

=head1 DESCRIPTION

This test checks your code against Perl::Critic, which is a implementation of
a subset of the Perl Best Practices.

It's severity can be controlled using the severity parameter in the use
statement. 5 being the lowest and 1 being the highests.

Setting the severity higher, indicates level of strictness

Over the following range:

=over

=item gentle (5)

=item stern (4)

=item harsh (3)

=item cruel (2)

=item brutal (1)

=back

So gentle would only catch severity 5 issues.

Since this tests tests all packages in your distribution, perlcritic
command line tool can be used in addition.
