# History:

# 2017-12-02, Benjamin Roberts <benjamin@bgroberts.id.au>:

# version 0.4: added support for home path expansion

# 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
