# AutoBotchk, (C)1999 Jeff Fisher (guppy@eggheads.org)
#
# updates
# -------
#  03Feb99: wrote the first version and it worked
#  04Feb99: made it easier to use, how? ./autobotchk
#           <config> will create the botchk and crontab
#           automatically, no command line options now.
#  20Feb99: added a '-noemail' setting for [s]
#
# how to use
# ----------
#  well, first you need to put the program into your Eggdrop
#  directory (the one you run from hopefully). then you should
#  probably type 'chmod u+x autobotchk' so the file permissions
#  are set correctly. and finally, type './autobotchk <config>'
#  replacing <config> with the name of your config file right?
#
#  in 1.05z, because of [z], you can now specify the bot directory
#  to use, for example, './autobotchk eggdrop.conf -dir /home/bot'
#  this now allows you to run the program from any dir :P~
#
# other Stuff
# -----------
# [22:36] <cHr|s`> when you type ./autobotchk without any options, it should give you the menu
# [22:36] <cHr|s`> like the nukes do
#  ^ -- he might be Urkel, but we love him anyways ..
# [18:10] <[z]> nope...came back weith can't crontab -l error
#  ^ -- no one said this script was perfect, mmmm z's wife
# [19:27] <[z]> also guppy..would be nice if i could reference my bots directories ;)
#  ^ -- just when I finished 1.05 :P
# [18:50] <[s]> how to set the autobotchk not to recieve e-mails about the cron ??
# [18:51] <slennox> add >/dev/null 2>&1 to the end of the crontab entry
# [18:52] <[s]> what crontab
# [18:52] <[s]> i have gupy's script
# [18:52] <[s]> autobotchk
