I disagree - there's something icky about a tool generating files
I didn't request - if I tell bison to make me a grammar in foo.cc
from foo.yy I do not expect to get 3 header files generated for me
as well - especially if that list of additional files is not stable
across bison versions (and I suspect that will be the case, especially
for skeletons that evolve).
At the very least bison should provide an option (--clean?) that cleans
up after itself properly.
