Message:

• Cosmetic changes to trace_help() output
• inclusion of some m4 handlers to deal with swig and python, lifted from ​http://autoconf-archive.cryp.to/. These are GPLd, which needs to be taken into account if libtrace licensing changes!
• updated the swig bindings for python. Mostly api compliant now. Still possibly a memory leak to do with displaying ip addresses - I haven't touched this particular part of the code yet.
