55: This is a WWW interface to the FreeBSD CVS tree.
56: You can browse the file hierarchy by picking directories
57: (which have slashes after them, e.g. <b>src/</b>).
58: If you pick a file, you will see the revision history
59: for that file.
60: Selecting a revision number will download that revision of
61: the file. There is a link at each revision to display
62: diffs between that revision and the previous one, and
63: a form at the bottom of the page that allows you to
64: display diffs between arbitrary revisions.
