#
# BitchX CTCP and AWAY simulator with built-in CTCP flood protection.
#
# Simulates BitchX 75p1+ and 75p3+ CTCP replies. The version is randomly
# selected on startup. Note that this script doesn't replace the CTCP
# module - the CTCP module must be loaded for it to work.
#
# DCC command .bitchx (for global +m/n/t users) displays basic info about
# current script status.
#
# This script was originally based on bitchxpack.tcl by DeathHand.

# Flood protection setting in number:seconds:disable format. By default, if
# the bot receives 5 CTCPs in 30 seconds, it will stop responding to all
# CTCPs for 120 seconds.
set bx_flood 5:30:60

# Simulate BitchX AWAY mode? 1 to enable, 0 to disable.
set bx_away 1
