ACARS decoder

Acarsdec is an open source, multi-channels realtime ACARS decoder for Linux.

It features :
- up to four channels decoded simultaneously
- error detection AND correction
- input from sound file , alsa sound card or software defined radio (SRD) via a rtl dongle (http://sdr.osmocom.org/trac/wiki/rtl-sdr) or airspy (http://www.airspy.com)
- could send decoded acars to a server via UDP in planeploter format or its own dedicated format.

The 4 channels decoding is particularly useful with the rtl dongle. It allows to directly listen simultaneously to 4 different frequencies , with a very low cost hardware.

Since version 3.0, acarsdec comes with acarsserv : a database backend program to store received acars messages.
