The main.c is currently a test stub, reading from a file, printing on
stdout, but fixing that into something usable for 26c3 shouldn't be long.
I'm working on SMS and ciphering right now but at worse I could write
something up in the plane or the day just before.

The plan was to have a daemon running that would essentially play the role
of the LCS, mapping a tcp session to a RRLP session. This way I could have
re-used the same code for both openbsc/openbts.

It also misses the Reference Position decoding/encoding (currently my home
GPS coordinates are hardcoded :), I'll have to fix that.

BTW, when do you setup the network ? I should be in Berlin the 26th late
afternoon if you need help setup/pre-testing.

Not at all, that's what it was written for :)
