+ This is a WWW interface for CVS Repositories.
+ 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.
