# This is a shell script for cycling exim main and reject log files. Each time
# it is run, the files get "shuffled down" by one, the current one (e.g.
# mainlog) becoming mainlog.01, the previous mainlog.01 becoming mainlog.02,
# and so on, up to the limit configured here. When the number to keep is
# greater than 99 (not common, but some people do it), three digits are used
# (e.g. mainlog.001). The same shuffling happens to the reject logs. All
# renamed files with numbers greater than 1 are compressed.
