rtorrent's web site has this example of a configuration rule to move a completed torrent:
system.method.set_key = event.download.finished,move_complete,"execute=mv,-u,$d.get_base_path=,~/Download/;d.set_directory=~/Download/"
Is the format of this command documented anywhere? I cannot find what
$d.get_base_path means anywhere, or why it's
$d in one spot and just
d in another spot, for example.
