+   Regular expressions are a way of describing a pattern - for example, "all the words
+   that begin with the letter A" or "every 10-digit phone number" or even "Every sentence
+   with two commas in it, and no capital letter Q".  Regular expressions (aka "regexp"s)
+   are useful in Apache because they let you apply certain attributes against collections
+   of files or resources in very flexible ways - for example, all .gif and .jpg files under
+   any "images" directory could be written as /.*\/images\/.*[jpg|gif]/.
+
+   <P>The best overview around is probably the one which comes with
+   Perl.  We implement a simple subset of Perl's regexp support, but
+   it's still a good way to learn what they mean.  You can start by
+   going to the <A
+   HREF="http://www.perl.com/CPAN-local/doc/manual/html/pod/perlre.html#Version_8_Regular_Expresions">CPAN
+   page on regular expressions</A>, and branching out from there.
