It's a tricky area though in terms of what is best, providing no functions, vs. providing functions that do nothing and succeed, vs. providing functions that do nothing and fail, vs. providing a more explicit way to query if the functionality is provided, as well as deciding between build-time vs. run-time checks (we don't have anything like autoconf in our system, for better and worse).

Yes, monotone...  I'm trying to organise putting together the monotone 
repository, and it seems that the first thing to do is to get a local 
copy of the existing modula 3 CVS repository to experiment on.  There 
are at least two ways to go about putting the monotone repository 
together, on of them seems to requre me to have a local copy of the 
repository.

I suspect I need to get cvsup running to make this local copy of the 
CVS.  Where should I get cvsup?  (It doesn't seem to be distributed as a 
Debian package; perhaps that's because Modula 3 ins't either?)  Did you 
make changes to cvsup to get it to work on current versions of Modula 3?
If so I should probably get the changed version.

Or else maybe someone could make a .tgz file out of the entire cm3 CVS
and I could download and work with that?
