Problems with ctm-cvs-cur

Tonight cvs-cur didn't create a delta.  The reason is that cvsup
deleted most of the contents of "www" without putting them into any
kind of "Attic."  The program that generates the delta only allows up
to 2500 files to be deleted in any one delta.  Presumably this is to
avoid problems if huge numbers of files are deleted accidentally at
the other end.  And this is quite likely what really happened.

I would like to encourage people to move to svn-cur.  I have been
testing it for quite a while now, and it seems to be working very well.

cvs-cur is a rather hard set of deltas to maintain, particularly now
that FreeBSD is no longer based upon cvs.  Just in terms of generating
deltas, it takes about 2 hours to create.  Whereas the typical svn-cur
delta takes less than a minute to create (the really big ones take at
most 5 minutes to create).

Also, cvs-cur is hard to maintain because it is the most troublesome.
 As I have said, I plan to get rid of cvs-cur around the end of
February.  And when it goes I will be very relieved.

In the meantime, I really don't know what caused the last breakage,
and I cannot predict if it will fix itself tomorrow, or whether it
will remain broken for quite a while.  As I said, I don't think the
problem is at my end,

Thanks, Stephen
