=head1 NAME

Perl::Critic::Policy::Bangs::ProhibitFlagComments - Don't use XXX, TODO, or FIXME.

=head1 AFFILIATION

This Policy is part of the L<Perl::Critic::Bangs> distribution.

=head1 DESCRIPTION

Programmers often leave comments intended to "flag" themselves to
problems later. This policy looks for comments containing 'XXX',
'TODO', or 'FIXME'.

=head1 CONFIGURATION

By default, this policy only looks for 'XXX', 'TODO', or 'FIXME' in
comments. You can override this by specifying a value for C<keywords>
in your F<.perlcriticrc> file like this:

  [Bangs::ProhibitFlagComments]
  keywords = XXX TODO FIXME BUG REVIEW
