# 2012-08-28, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.3: compatibility with WeeChat >= 0.3.9 (hdata_time is now long instead of string)
# 2012-08-23, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.2: use hdata for WeeChat >= 0.3.6 (improve performance)
# 2009-06-10, xt <tor@bash.no>
# version 0.1: initial release
