# This script searches in RIPPINGDIR for running
# sessions of 'abcde' and prints out the abcde-jobs
# that are unfinished and the number of encoding- and
# ripping-jobs running.

# NOTE: this script is a quickhack and you should adopt it to your needs!
# Once again: REQUIRES MODIFYING!
# 2do:
#   * check, if used tools are installed
#   * check, if there is something to check ;-)
