# Documentation generator for WeeChat: build include files with commands,
# options, infos, infolists, hdata and completions for WeeChat core and
# plugins.
#
# Instructions to build config files yourself in WeeChat directories (replace
# all paths with your path to WeeChat):
#     1.  run WeeChat and load this script, with following command:
#           /python load ~/src/weechat/doc/docgen.py
#     2.  change path to build in your doc/ directory:
#           /set plugins.var.python.docgen.path "~/src/weechat/doc"
#     3.  run docgen command:
#           /docgen
# Note: it is recommended to load only this script when building doc.
# Files should be in ~/src/weechat/doc/xx/autogen/ (where xx is language).
