Hi Maxim,

You are right, the code often checks the skeleton name to decide
what's to be done.  We could add calls to basename to avoid the
dependency on the directory name, yet that would mean we can no
longer tell the difference between glr.c from Bison itself, and
something that would be customized by the user.

I suppose the clashes between user skeletons and Bison skeletons
are unlikely, or precisely on purpose, in which case we could
decide to use basename, indeed.
