This is a WWW to the Retro City iNTERnET BBS public CVS repositories. You can browse the file hierarchy by following directory links (which have slashes after them, e.g. src/). If you follow a link to a file, you will see its revision history. Following a link labeled with a revision number will display that revision of the file. In the revision history view, there is a link near 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.
