[BRLTTY] Fwd: Orca crash with grade 2 and latest versions of brltty and liblouis

[Michael Whapples]

I believe also some of the systems used to ease creating bindings/python 
extensions can allow calling python code or having python functions for 
callback functions. I'm quite certain pyrex does allow this, I'm not so 
sure whether swig does (although with swig you could go to telling it to 
insert the C code as suggested by Mario).

What system is used for creating the brltty bindings?
