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