m3swig -- is high modified by Peter McKinna "SWIG for Modula-3".

m3swig is very useful. Tested on .h from LLVM 11.0.1, LLVM 10.0.1, LLVM 9.0.1 by myself ( i.e. V.V.M.);
on .h files of LLVM 9.0.0 and LLVM 8.0.X by Peter McKinna.

Early m3swig versions have been "good working" with .h files of QT 4.X
