NP. My original message wasn't identified as anything to do with SWIG.

Once I knew what to look for, this article popped up onto my radar!

I well know what you mean! Contrast with the reams of documentation for
the Java interface. However, aside from the -declaremodule bit, it's just
about sufficient for an experienced (wearied) user.

I've got 160 symbols (constants and functions) to wrap -- so I'll be using
the tool for that!
However, SWIG doesn't play nice with 3m (I think it's a bit more the case
that the C grammar accepted by ``raco ctool -xform'' is a bit too limited
to cope with SWIG wrapper code).
More frustrating is that SWIG offer a *LISP* CFFI wrapper.
I would love to see it produce a racket FFI module -- I'd hope the code to
be far cleaner than these C middle-layer wrappers.
Is there a CFFI -> racket FFI conversion floating about in the world of
men?
