 <p>
 This is a WWW interface to the !!CVSROOTdescr!! CVS tree.
 You can browse the file hierarchy by picking directories
 (which have slashes after them, <i>e.g.</i>, <b>src/</b>).
 If you pick a file, you will see the revision history
 for that file.
 Selecting a revision number will download that revision of
 the file.  There is a link at each revision to display
 diffs between that revision and the previous one, and
 a form at the bottom of the page that allows you to
 display diffs between arbitrary revisions.
