Question: wmClearcase emulation

Hello all,

our intention is to put a subversion client behind WmClearCase.
Can you help us out with ideas or concrete ways to procede?

We found out that WmClearCase doesn’t use the commandline-tools of
rational clearcase to submit changes. Our presumption is that it uses
the so called CAL interface of rational cc. Do you know of a way to
access and use this interface or do you know if it really uses it or not?

I would appreciate any input to this subject, starting with
a CAL API (if existant?) or some ideas how to solve our problem.

Best regards
