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