# This is a really simple script intended to be run as an action
# from transmission-remote-gtk. It uses rsync to fetch
# a torrent/torrents to a local directory (or put it somewhere
# remote and run it using ssh to there).

# It also shows how we can call transmission-remote with
# connection details to find information about a torrent or
# manipulate it.

# Example
# gnome-terminal -e "tpull.sh %{hostname} %{port} %{username}:%{password} %{id}[,] /srv/incoming/"
