# xchat-inputcount.pl: add a character count next to xchat's input box.
# (useful when twittering, to see if you are within 140 characters)
#
# usage: Xchat / Load plugin...
#
# prereqs: libgtk2-perl
#
# bug: character count lags one keypress behind the actual input. Press
# any key (e.g. Ctrl, Shift, arrow keys) to cause the count to be updated.
