#
# 2016-02-27: nils_2, (freenode.#weechat)
#       0.3 : make script consistent with "buffer_switch_autojoin" option (idea haasn)
#
# 2013-11-07: nils_2, (freenode.#weechat)
#       0.2 : fix file not found error (reported by calcifea)
#           : make script compatible with Python 3.x
#
# 2013-07-26: nils_2, (freenode.#weechat)
#       0.1 : initial release
#
# script will create a config file (~./weechat/queryman.txt)
# format: "servername nickname" (without "")
#
# Development is currently hosted at
