+# This is a script suitable for use in a crontab.  It checks to make sure
+# your bot is running.  YOU NEED A SEPARATE CRON JOB FOR EACH BOT.  If your
+# bot isn't found, it'll try to start it back up.
+#
+# You'll need to edit this script for your bot.
+#
+# To check for your bot every 10 minutes, put the following line in your
+# crontab:
+#    0,10,20,30,40,50 * * * *   /home/mydir/mybot/botchk
+# And if you don't want to get email from crontab when it checks you bot,
+# put the following in your crontab:
+#    0,10,20,30,40,50 * * * *   /home/mydir/mybot/botchk >/dev/null 2>&1
+#
+
+# change this to the directory you run your bot from (capitalization COUNTS):
+botdir="/home/mydir/mybot"
+
+# change this to the name of your bot's config file (capitalization COUNTS):
+botscript="mybot"
+
+# change this to the botnet-nick of your bot (capitalization COUNTS):
+botname="LamestBot"
+
+# change this to the name of your bot's userfile (capitalization COUNTS):
+userfile="LamestBot.user"
+
+# change this to the name of your bot's pidfile (capitalization COUNTS):
+pidfile="pid.LamestBot"
+
+########## you probably don't need to change anything below here ##########
