I feel compelled to defend arch's honor at this point.  This
particular problem (of "larch move" not actually moving files, just
metadata), has been fixed for several weeks.  And no, it didn't break
anything when it was fixed.

Arch does have problems right now, but reliability is not one of them.
I don't know of any circumstances where data has been lost.

The biggest problem is that arch is slow.  Also, it's documentation is
sub-par.  Finally, it doesn't have a real, end-to-end integrity check.
It only has integrity checks for individual patch-sets.  But I want to
emphasize that we don't know of anyone who has lost data.

Arch has supported since the beginning basically all of the operations
that bitkeeper has.  It just doesn't have the fancy gui and a few of
the convenience functions.

Since Tom Lord stopped working on arch, development has continued at
