+=head1 NAME
+
+Perl::Critic::Policy::RegularExpressions::RequireExtendedFormatting - Always use the C</x> modifier with regular expressions.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+Extended regular expression formatting allows you mix whitespace and
+comments into the pattern, thus making them much more readable.
+
+    # Match a single-quoted string efficiently...
+
+    m{'[^\\']*(?:\\.[^\\']*)*'};  #Huh?
+
+    #Same thing with extended format...
+
+    m{ '           #an opening single quote
+       [^\\']      #any non-special chars (i.e. not backslash or single quote)
+       (?:         #then all of...
+          \\ .     #   any explicitly backslashed char
+          [^\\']*  #   followed by an non-special chars
+       )*          #...repeated zero or more times
+       '           # a closing single quote
+     }x;
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
+
+
+=head1 NOTES
+
+For common regular expressions like e-mail addresses, phone numbers,
+dates, etc., have a look at the L<Regex::Common> module.  Also, be
+cautions about slapping modifier flags onto existing regular
+expressions, as they can drastically alter their meaning.  See
+L<http://www.perlmonks.org/?node_id=484238> for an interesting
+discussion on the effects of blindly modifying regular expression
+flags.
