# Description:
#     recoverop.pl tries to take a channel operator privilege by part and join
#     after last user leave a channel. After loading the script, by default, it
#     is unavailable for all channels. You can specify server and channel in
#     which the script is available by perl regular expression.
#
# Vars:
#     plugins.var.perl.recoverop.regex
#         perl regular expression (format: "server.channel") make recoverop.pl
#         available.
#     plugins.var.perl.recoverop.modes
#         modes for channel (format: "+sn"), empty string or not set == do not change modes
#
# Examples:
#     /set plugins.var.perl.recoverop.regex "\A(freenode\.#weechat)|(oftc\.#debian.*)\Z"
#         try to recover channel operator privilege in #weechat on freenode and
#         in all channels starting from "#debian" on oftc.
#     /set plugins.var.perl.recoverop.regex ".*"
#         recoverop is available for all channels.
#     /set plugins.var.perl.recoverop.regex ""
#         recoverop is unavailable for all channels.
#     /unset plugins.var.perl.recoverop.regex
#         recoverop is unavailable for all channels (default).
#     /set plugins.var.perl.recoverop.modes "+sn"
#         set modes +sn after join.
