# Program : sms_users                          Host : zenobe
# Author  : Philippe Andersson
# Date    : 20/11/98
# Version : 1.3
# Notice  : (c) Les Ateliers du Heron, 1996 for Scitex Europe, S.A.
# Comment : Extract statistics from system logs for SMS subsys.
#           Count number of messages sent by each user and
#           print results on stdout.
# History :
# * 1.0 (23/10/98) : Initial release.
# * 1.1 (03/11/98) : Added handling for -f parameter.
# * 1.2 (18/11/98) : Modified the call to sort in order to get
#   the users sorted by usage, heaviest users first.
# * 1.3 (20/11/98) : Finally found the options to get the sort
#   feature right.
