# -----------------------
#
# '<unique name>': 
#  mode: r                      # modus i for interactiv (botcommands) or r for readonly - ir = interactiv + request mode
#  channelbotname: name         # overwrites pandabot.conf:botcommand eg. eva, adam or ... default is pandabot.conf:botcommand 
#  autosync: true 				# or false - is false by default - ATTENTION! TARGET CHANNEL SHOULD BE FULL READ @ DATABASE!                                                 
#  disabled: true 				# or updatedb or false - is false by default
#  from: <channelid>            # from:type:topicid - forward only files from specificated topic
#  to:
#   - <channelid1>
#   - <channelid2>:topic:<topicid>                   # send forwards in topic
#   - <channelid3>
#   - <channelid4>
#   - ...
#
# redirectout: <channelid>:<link|id>:<targetchannelid> # means print search/ last results from another channel(<channelid>) to current channel
# is <targetchannelid> configured, he will search in channelid and forward to targetchannelid
# eg. channel1: search in channelid and will forward to targetchannelid
# use !<botname> last<x> channel:current to list last<x> entrys in current channel
# use !<botname> search <term> channel:current to search in current channel
#
# repostinfomsg: <msgid>:<time>:<timemode>:<topic> # eg. repostinfomsg: 1234:5:minutes:-1 (-1 no topic, otherwise topicid)
# <timemode>: seconds, minutes, hours, days - min. reposttime: 30 minutes
#
# types can only be setup @ from: 
# from: <channelid>                # set default video
# from: <channelid>:mp3            # set type to mp3
# from: <channelid>:movie:topicid  # set type to movie only from topicid 
#
# valid types are: mp3, flac, audio, audiobooks, ebooks, movie, moviefhd, movie4gb, archive, video - default video (means video files with an minimum duration from 15 minutes)
# all audio types: have no min. duration, movie: min. duration 75 minutes
# moviefhd: movie fhd(+) and min size 1.7gb, movie4gb min size 2.5 gb  
# archive: zip, rar, zZ and so on...
