+=head1 NAME
+
+Perl::Critic::Policy::Miscellanea::RequireRcsKeywords - Put source-control keywords in every file.
+
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic|Perl::Critic>
+distribution.
+
+
+=head1 DESCRIPTION
+
+Every code file, no matter how small, should be kept in a
+source-control repository.  Adding the magical RCS keywords to your
+file helps the reader know where the file comes from, in case he or
+she needs to modify it.  This Policy scans your file for comments that
+look like this:
+
+    # $Revision: 4106 $
+    # $Source: /myproject/lib/foo.pm $
+
+A common practice is to use the C<Revision> keyword to automatically
+define the C<$VERSION> variable like this:
+
+    our ($VERSION) = '$Revision: 4106 $' =~ m{ \$Revision: \s+ (\S+) }x;
+
+
+=head1 CONFIGURATION
+
+By default, this policy only requires the C<Revision>, C<Source>, and
+C<Date> keywords.  To specify alternate keywords, specify a value for
+C<keywords> of a whitespace delimited series of keywords (without the
+dollar-signs).  This would look something like the following in a
+F<.perlcriticrc> file:
+
+    [Miscellanea::RequireRcsKeywords]
+    keywords = Revision Source Date Author Id
+
+See the documentation on RCS for a list of supported keywords.  Many
+source control systems are descended from RCS, so the keywords
+supported by CVS and Subversion are probably the same.
