Yes, of course.  It only mirrors individual files and it's not
terribly efficient -- a better implementation would rewrite the
ed-style diffs into RCS-style diffs, combine them, and apply them to
the stored file in a single pass.  But even in its current
implementation, it's better than downloading the whole file every day.
