Correct the email address that folk are to bug if they need
help; also point them in the direction of the source, not PHK (or any other human) if they need to make CTM deltas of their own.

How do I make a CTM-delta ?

---------------------------

Don't. Send me email before you even try. This is yet not quite as trivial
|

as I would like. This is not to discourage you from using CTM, it is merely
|

to warn you that it is slightly tedious and takes much diskspace.

Read the source, and be prepared to have 2 copies of the tree; One is

the reference ("From") tree, and the other is the delta ("To") tree.

The mkCTM script will create the CTM diff of the differences between

the reference tree and the delta tree. A lot of scratch space is

required, and your machine will work hard.

Because CVSUP has improved on the concept quite a bit, and is now

the method of choice.
