Open source / downloadable compiler for Executable UML?

I've started reading through "Executable UML: A Foundation for
Model-Driven Architecture" and would /really/ like to start applying
the concepts. The book mentions BridgePoint as a model compiler which
can be downloaded to execute the examples in the book, but I cannot
find a link on the projtech.com site - it appears that it is no longer
being offered for download.

Are there any open source or downloadable model compilers which I can
use to compile and execute the models in the book, and play with my
own? I've done some Googling, and there is a daunting array of projects
out there which purport to relate in some way to MDA or Executable UML,
but are not what I'm looking for. I'm starting to think there's nothing
out there for me to play with that doesn't cost more than I'll earn in
the next three years.

Do I have any options?
