[BRLTTY] introduction

[kendell clark]

hi
I've added the debug log level and a log path to my brltty config file.
I have a debug log file for anyone who is interested. Should I attach it
to an email or upload to a pastebin? I attempted to load the following
speech drivers in order: vv, espeak, and finally sd. I checked
/usr/lib/brltty, and neither libbrlttysd.so nor libbrlttyvv.so exist,
but brlttyes.so does, as does libbrlttyfv.so, so it looks like   the
speech dispatcher driver isn't being built. I'll look at the readme file
again. Is there a git repository I can clone to follow brltty
development? This would help me better keep up with new brltty releases
so I can keep the brltty package up to date in my linux distribution.
Thanks
Kendell Clark
