2 * The rcs log will be removed for `real' releases
4 * A note about version numberering: Since RCS is notable faster when using
5 * trunk revisions (x.y), I have decided simply to start with revs 1.x
7 * There is a small bug in CVS that prevents the commit -r option from
8 * working. This means that the revision numbers in the individual files
9 * do not agree with the one in the log. I hope to fix this some time soon.
