#       socket          rTorrent's rpc socket (scgi_local)      - using scgi_local      - needed, when "src" is set to "socket"

#       diff            "yes" for using bps for upload and Bps for download, or anything else for using Bps for both

#

#

# Configuration example

#

#       [rtom_allsessions_*]

#       user username

#       env.src socket

#       env.socket /home/user/torrent/.socket/rpc.socket,/home/user/torrent/.socket/rpc.socket

#       env.category Category

#

#       [rtom_allsessions_*]

#       user username

#       env.port 5000,5001,5002,5003
