Oh, I see.  I did not immediately realize that this was a generated
recipe.

I think this should rather be done by the guile-build-system.  We
already do this in other build systems such as python-build-system.

This seems to be the best way forward.

I had a few more changes that I intended to push but then stopped to
write you.  In the case of guile-hall I think the wrapping could be
greatly simplified, but that would not necessarily be possible in the
generic case.  If we add this behaviour to the guile-build-system,
however, Hall would not have to do any of this and the package
definition could become simpler.

I’m excited about Hall and would love to add support for it in Guile
Studio (e.g. through a menu in the menu bar).
