There's a lot of ex-EOF/ex-WO folks involved with this project (including m=
e).

Do we still have the model converter out there?  When I started using
Cayenne back in the 1.1 days, we had a converter tool that would
create a cayenne project out of an EOF project.   I'm not sure if it's
still around or if it needs to be updated -- even back then there were
some rough edges.
