# script to highlight adb logcat output for console
# written by jeff sharkey, http://jsharkey.org/
# piping detection and popen() added by other android team members
# modified by Josh Guilfoyle <jasta@devtcg.org> to simplify formatting back to
# adb logcat original. I just want colorized logcat output, nothing fancier.
