How is the semantic relationship between the .vapi name and its library?
  s/^lib//; s/\.a$//; s/$/.vapi/    ?

What about shared libraries, do they have .vapi's, too?

What if I want to build one big shared (or static) library from a set of
convenience archives (uninstalled .a libraries with PIC code)?  Do you
have means to generate a .vapi for the big library from the .vapi's of
the several small ones (plus maybe a couple of loose objects, too)?

Just trying to find out how far we can push it.

Thanks,
