FlexGet is a multipurpose automation tool for content like torrents,
nzbs, podcasts, comics, etc. FlexGet is able to handle different kinds
of sources like RSS-feeds, html pages and csv files. There are even some
plugins for sites that do not provide any kind of useful feeds.

FlexGet is extremely useful in conjunction with applications which have
watch directory support, such as rtorrent.
