+# Getops 2.3b

+# $Id: getops.tcl,v 1.18 2003/03/26 00:19:30 wcc Exp $
+
+# This script is used for bots to request and give ops to each other.
+# For this to work, you'll need:
+
+# - Bots must be linked in a botnet
+# - Every bot that should be ops on your channels must load this script
+# - Add all bots you wanna op with this one using the .+bot nick address
+#   command. The "nick" should be exactly the botnet-nick of the other bot
+# - Add the hostmasks that uniquely identify this bot on IRC
+# - Add a global or channel +o flag on all bots to be opped
+# - Do exactly the same on all other bots
+
+# The security of this relies on the fact that the bot which wants to have
+# ops must be 1) linked to the current botnet (which requires a password),
+# 2) have an entry with +o on the bot that he wants ops from and 3) must match
+# the hostmask that is stored on each bots userfile (so it is good to keep the
+# hostmasks up-to-date).

+# 2.3c by PPSlim <ppslim@ntlworld.com>
+#  - Small fix on timer hanlding.
+#    Not list formatted, allowing command parsing of channel name
+
+# 2.3b by gregul <unknown>
+#  - small fix in getbot
+
+# 2.3a by guppy <guppy@eggheads.org>
+#  - fix for bind need
+
+# 2.3 by guppy <guppy@eggheads.org>
+#  - minor cleanup to use some 1.6 tcl functions
+#  - use bind need over need-op, need-invite, etc ...
+
+# 2.2g by poptix <poptix@poptix.net>
+#  - Fabian's 2.2e broke the script, fixed.
+
+# 2.2f by Eule <eule@berlin.snafu.de>
+#  - removed key work-around added in 2.2d as eggdrop now handles this
+#    correctly.
+
+# 2.2e by Fabian <fknittel@gmx.de>
+#  - added support for !channels (so-called ID-channels), using chandname2name
+#    functions. This makes it eggdrop 1.5+ specific.
+
+# 2.2d by brainsick <brnsck@mail.earthlink.net>
+#  - Undernet now handles keys differently.  It no longer gives the key on a
+#    join, but instead gives it on an op, but eggdrop doesn't check for this.
+#    getops-2.2d should now handle this correctly.  (This should be the final
+#    fix to the key problems.)
+
+# 2.2c by Progfou (Jean Christophe ANDRE <progfou@rumiko.info.unicaen.fr>)
+#  - changed "Requested" to "Requesting" as it was a little confusing
+#  - corrected the "I am not on chan..." problem with key request
+#    (thanks to Kram |FL| and Gael for reporting it)
+#  - removed more unnecessary check
+
+# 2.2b by Progfou (Jean Christophe ANDRE <progfou@rumiko.info.unicaen.fr>)
+#  - removed global +o in unknown bot test
+#  - removed unnecessary checks due to previous unknown bot test
+
+# 2.2a by Progfou (Jean Christophe ANDRE <progfou@rumiko.info.unicaen.fr>)
+#  - removed Polish language!
+
+# 2.2 by Cron (Arkadiusz Miskiewicz <misiek@zsz2.starachowice.pl>)
+#  - works good (tested on eggdrop 1.3.11)
+#  - asks from unknown (and bots without +bo) are ignored
+#  - all messages in Polish language
+#  - better response from script to users
+#  - fixed several bugs
+
+# 2.1 by Ernst
+# - asks for ops right after joining the channel: no wait anymore
+# - sets "need-op/need-invite/etc" config right after joining dynamic channels
+# - fixed "You aren't +o" being replied when other bot isn't even on channel
+# - better response from bots, in case something went wrong
+#   (for example if bot is not recognized (hostmask) when asking for ops)
+# - removed several no-more-used variables
+# - added the information and description above
+
+# 2.0.1 by beldin (1.3.x ONLY version)
+# - actually, iso needed to be modded for 1.3 :P, and validchan is builtin
+#   and I'll tidy a couple of functions up to
+
+# 2.0 by DarkDruid
+# - It'll work with dynamic channels(dan is a dork for making it not..)
+# - It will also only ask one bot at a time for ops so there won't be any more
+#   annoying mode floods, and it's more secure that way
+# - I also took that annoying wallop and resynch stuff out :P
+# - And I guess this will with with 1.3.x too
+
+# Previously by The_O, dtM.
