 <p>(For programmers only) If you know your way around a <link href="https://secure.wikimedia.org/wikipedia/en/wiki/Regular_expression">regex</link>, or regular expression, this option allows you to search for complex patterns of letters, so that you can find, for example, all words that start with a and end with m, and are between six and fifteen letters long, or all messages that declare a particular header twice. For information about how to use regular expressions, check the man page for the grep command.</p></item>
