I have ;-)

Yes. It will become unsuitable soon, but you'll know when that 
happens.

There is, if you're willing to use cvs directly. Get cygwin 
(www.cygwin.com) or WinCVS. You might find cygwin easier to use 
because it has a unix command-line interface, which matches the 
instructions at SourceForge.

Right.

Oops, I need to fix the mv/copy thing. Thanks for the heads-up.

No, it doesn't really. If you set COMO_INCLUDE_PATH and 
COMO_STDLIB_PATH (in your environment or on Jam's command-line) you 
can use libcomo without modifying the jam file.

Dale, I can't be sure what your problem is, but I can tell you this: 
I had a REALLY hard time getting como installed and running correctly 
on my system. I had lots of correspondence with comeau tech support 
before it all worked right. I suggest that you copy the command-lines 
generated by Jam when you try to build things with comeau, and paste 
them into a .bat file. Then strip them down until you can get 
something to build. If you can't even get a simple hello, world to 
separately compile/link, you should assume the problem is your 
installation: time to contact comeau. Otherwise, you should be able 
to see where the build system is getting it wrong.

Try the COMO_STDLIB_PATH/COMO_INCLUDE_PATH setting above first, 
however.
