[BRLTTY] Footsteps towards better accessibility in Linux

[kperry at blinksoft.com]

To be clear NVDA has more than just python and c++ and would be very hard to
compare that beast.  Here is the break  down off all the files in the
development tree for NVDA for nerds like me.

	I'm not yet familiar with Orca, but to say NVDA is written in python
is misleading.  Most of it is in python, but there are core portions which
are written in C++.  So, yes, I would say that if Orca is written purely in
python, it probably does affect its performance.
