So does qucs invoke the C compiler?  Or is it FreeHDL?  Or the user?

That one that invokes the C compiler should have its fine name
hard-coded.  Well, except if it’s the user.  ;-)

Hard-coding is preferable over propagation, to avoid “polluting” user
profiles.

I think we shouldn’t abuse descriptions to give instructions.  It should
Just Work, as much as possible.

(Though I reckon that in some cases it would be nice to associate an
message with packages that would be displayed upon installation.)

Thanks,
