# You can specify your configuration in a different file 
# (so that it is saved with upgrades, saved in your home directory,
# or whateve reason you want to)
# by commenting out/deleting the configuration lines and placing them
# in a text file (say /home/user/.rtorrent.init.conf) exactly as you would
# have written them here (you can leave the comments if you desire
# and then uncommenting the following line correcting the path/filename 
# for the one you used. note the space after the ".".
# . /etc/rtorrent.init.conf

#Do not put a space on either side of the equal signs e.g.
# system user to run as
user="'''andrew'''"

# the system group to run as, not implemented, see start for beginning implementation
# group=`id -ng "$user"`

# the full path to the filename where you store your rtorrent configuration
config="`su -c 'echo $HOME' $user`/.rtorrent.rc"

# set of options to run with
options=""

# default directory for screen, needs to be an absolute path
base="`su -c 'echo $HOME' $user`"

# name of screen session
srnname="rtorrent"

# file to log to (makes for easier debugging if something goes wrong)
