Hi!

No, not really. antlr is public domain [1] so no distribution restrictions 
apply
and we have xcopy deployment so it's really a burden.

Yes. boo is developed and tested in both Windows and GNU/Linux. The
parser was never a problem.

The generated scanners will have a dependency on the antlr runtime. I prefer 
to distribute
the runtime as an external assembly (antlr.runtime.dll) but I've seen people 
embedding the
source files in their own project as well. Both approaches work and are 
conform to
the license.

Cheers,
