DOC_CONTENTS="\
If you use transmission-daemon, please, set 'rpc-username' and
'rpc-password' (in plain text, transmission-daemon will hash it on
start) in settings.json file located at /var/lib/transmission/config or
any other appropriate config directory.

Since µTP is enabled by default, transmission needs large kernel buffers for
the UDP socket. You can append following lines into /etc/sysctl.conf:

net.core.rmem_max = 4194304
net.core.wmem_max = 1048576

and run sysctl -p"
