# inspired by mrwright's nickcolor.pl and xt's colorize_nicks.pl
#
# you need nickcolor_expando or another nickcolor script providing the
# get_nick_color2 function
# Usage
# =====
# should start working once loaded
# Options
# =======
# /set colorize_nicks_skip_formats <num>
# * how many forms (blocks of irssi format codes or non-letters) to
# skip at the beginning of line before starting to colourise nicks
# (you usually want to skip the speaker's nick itself and the
# timestamp)
#
# /set colorize_nicks_ignore_list <words to ignore>
# * list of nicks (words) that should never be coloured
#
# /set colorize_nicks_repeat_formats <ON|OFF>
# * repeat the format stack from the beginning of line, enable when
# using per-line colours and colorize_nicks breaks it
# Commands
# ========
# you can use this alias:
#
# /alias nocolorize set colorize_nicks_ignore_list $colorize_nicks_ignore_list
#
# /nocolorize <nick>
# * quickly add nick to the bad word list of nicks that should not be
# colourised
