Hi!

I've created some scripts usefull for doing bitkeeper 2 cvs
gateway. I'm currently running them on nl.linux.org (as you can see
from the close look). I have not yet figured out how to export
resulting CVS to the world.

[These scripts are in CVS at www.sf.net/projects/linux25.]

Hopefully this will be usefull to someone...
