I can live with that.

It is not very consistent though. 
cvsnt does give an error message if you export a module with a
non-existent tag.
I request a module with a tag that does not exists in that particular
module, so I expect 
a similar error message. 
    cvs export -r FooBar a_module
    cvsnt [export aborted]: no such tag FooBar

It looks like an error message.  

The problem is that this is a confusing message.
If I, by mistake mispell a tag, I end up with cvs telling me that
it can not open a file for reading.  This leaves me with the impression
there is something wrong with my directory structure or file protection

This first happened under VMS, which has quite elaborate file protection
so I spend quite some time trying to figure out what was wrong. But
nothing was
wrong, it was just a misspelled tag.
