'''
This is a call/packet router for Homebrew Repeater Protocol and is based on
hblink.py. This is a very, very powerful program, but contains a complex
rule file. It can provide end-to-end activation of routing rules, and as
such, is very different from the "reflector" style of call "bridging" that
most hams are used to. Please see the rules file "hb_routing_rules-SAMPLE.py"
for a more complete explanation of how rules work.
This program currently only works with group voice calls.
