commit ec67d21540f1567bde5be08990184a80312710d1 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Sun Jul 8 21:21:44 2012 +0300
Move SerialICE LUA filter support to separate file
Isolate the existing LUA filtering. It does not meet my requirements for the modular filtering scripts, I will try to implement both in the same build side-by-side to maintain compatibility.
