Hmm. I wonder what's up with that. If you can't locate a copy, I'd be
glad to send you one. Or you can get it at
http://reefknot.sourceforge.net/ Looks like I need to upload the latest
version there.
And it is available out of CVS on sourceforge, if you want to submit
patches! :-)

Actually, Date::ICal does not do this, although we discussed it for
quite some time. The difficulty is knowing how long a month is. That may
sound like a silly question, but when you are dealing with non-gregorian
calendars that either don't have months, or have different-looking
months, it's hard to know what adding a month means.
However, that is a little bit of a cop-out, and hopefully we'll stop
waffling on this some time soon and add that functionality.
The syntax, by the way, looks more like:
$ical->add( month => 1 );
Or you can do stuff like:
$ical->add( week=>2, day=> 3, month=>-3 );
Except that the 'month' part of that does not actually work yet.

I suppose it's possible. However, I've also been asked to make it an
extension of every other date/time/oo/class object out there. Although I
had grand schemes of making this the universal date subclass, what it
has evolved into is more of just an ICal module, which certain other
modules that need ICal-ish things have subclassed off of. ICal is a
really convenient format for stuff like this.

Your syntax for all of this is really cool. Can we convince you to join
us in the Reefknot discussion and implement some of these in existing
modules? I'd rather see us extend something that is already out there
than add something else to the witches' brew.
