+ <para>
+ A regular expression, or "regex", is a way of describing a
+ string of text using metacharacters or wildcard symbols. For
+ example, the statement <userinput>fly*so[a|u]p</userinput> means
+ "any phrase beginning with 'fly' and ending in 'soup' or
+ 'soap'". If you searched for that expression, you'd find both
+ "fly in my soup" and "fly in my soap." There's not room here to
+ go into depth, but if you want, have a look at the documentation
+ for the <command>grep</command> command.
