Hole.io is a "blackhole" downloader for Put.io which does the following:

• Watches a "blackhole" directory for added torrent files
• Uploads the torrents to Put.io
• Watches the transfers for completion
• Downloads the completed files

Since I'm not dumb enough to intentionally check in my OAuth client secret for Put.io, you'll need to register an application to connect to Put.io. See https://put.io/v2/docs/gettingstarted.html#sign-up and https://put.io/v2/oauth2/register.

You will be able to enter these into the configuration page to get connected.

If you have subdirectories (one level deep) in the blackhole directory, they will be treated as "categories" and both Put.io transfers and the eventually downloaded files will be in subdirectories.
