# Extract collection & expiration statistics from Log file.
#
# From: Mark Moraes <moraes@csri.toronto.edu>
#
# Heavily modified by Kim F. Storm:
#  Added expiration statistics
#  Will now make daily statistics & grand summary
#  Split into two awk scripts to fit in argument list space
#  (and as a side-effect to be able to use functions in old awk!!!)
