# Translate string using Google translate API.
# (this script requires WeeChat >= 0.3.7)
#
# History:

# version 0.7: switch to json version of google translate api, support
# multiple sentences
# 2012-12-11, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.6: automatically replace old URL (not working any more) by new one
# 2012-10-13, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.5: fix call to translate API, use hook_process_hashtable
# (the script now requires WeeChat >= 0.3.7)
# 2012-01-03, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.4: make script compatible with Python 3.x
# 2011-08-20, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.3: fix typo in /help translate
# 2011-03-11, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.2: get python 2.x binary for hook_process (fix problem when
# python 3.x is default python version)
# 2009-10-15, Sebastien Helleu <flashcode@flashtux.org>:
# version 0.1: initial release
