16: This SQL based log class generates a SQL database and a set of tables storing
17: the results of a request. The result is stored in different tables depending
18: on whether it is information about the request or the resource returned.

20: This requires that you have linked against a <A href="http://www.tcx.se/">MySQL
21: library</A>. See the <A href="../../INSTALL.html">installation instructions</A>
