# Crontab script for ircstats2
#------------------------------
# You can use that script to check whether the stats generation script is
# running.
#
# No bugs are known in this software. So if it crashes, please tell me, even if
# you don't know anything about the crash !
#
# To check for your script every 10 minutes, put the following line in your
# crontab:
#    0,30 * * * *   /home/mydir/crontab.script
# And if you don't want to get email from crontab when it checks you script,
# put the following in your crontab:
#    0,30 * * * *   /home/mydir/crontab.script >/dev/null 2>&1
#

# change this to the directory you run the script from:
ircstatsdir="/home/lucas/ircstats2"

########## you probably don't need to change anything below here ##########
