The obvious problem that leaps to mind is that, if you are working
in any way with multiple platforms ("platforms" being defined as
Unix, MS Windows, and Mac), you will have potentially fatal line-ending
conversion.  This includes the popular option of Windows development
with a Linux CVS server (so the server can run on a reliable operating

There may be other problems, but I'm not thinking of them offhand.

If you can separate binary from text files based on file name, you
can use the "cvswrappers" file to specify binary files.  Write a
regular expression that matches, and follow it with "-k 'b'"
on each line.  (If all your files are binary, which is a bad fit
for CVS, it should at least be simple to write the regular

Since you're referring to your mods to vendor-supplied stuff, I
assume that you're dealing with some text files, as merging
local and vendor updates on binary files is *not* what CVS
does best.
