# Variables:
# /set kill_fake_gets_timeout X - if there is no tranfer in X minutes the get
# is closed
# Changes:
# 1.1 (2003.02.11)
# Hmm. The previous official version didn't worket at all (forgot to
# uncomment one line) and notbody told me that. Means nobody is using this
# script...
# Anyway, this should be fixed. And now it closes stalled gets as well.
