Hi Jim,

Thanks for getting back to us.

I only mentioned the CVS/* files because their state seems to be
related to the problem that we are observing. The problem can be
described without reference to them as follows:

When checking out directories *and* files from the top-level 
directory of the cvs repository, a later "cvs update" will not 
affect *all* packages.

Here is an example (directories 'ccd' and 'reco', plain file 'Makefile',
more shell output at the end of this message):

# Here, all works fine. Makefile is checked out first.
%cvs co Makefile ccd reco
%cvs update
cvs update: Updating ccd
cvs update: Updating reco

#Now the strange behaviour. Note that 'Makefile' is now 2nd.
%rm -rf *
%cvs co ccd Makefile reco
%cvs update
? ccd                     <-------- ccd is not updated !!
cvs update: Updating .
U .cvsignore
U Doxyfile
U recompile
cvs update: Updating reco

Regards,

Ulli
