Very nice, thank you so much!

Okay, beautiful.  You distribute these in Git too, right?

I'll be looking to make a new Mes release for Guix too, with Nyacc
unbundled.  For that, we need to package Nyacc and having `./configure
make install' would be the first step.  Do you have plans or ideas for
that?

If you want I could have a look and copy what I've for Mes, but Nyacc
can be much simpler.  I never use autotools but do try to conform to GNU
standards.
