With a friend.
For the pack of sheep.
A parcel of deers eating your garden.
A nest of rabbits is a fluffy place.
To properly test changes, I've been working for the past year on a CI and development environment for rtorrent.
The vagrant effort turned out unsuitable for testing due to the messiness involved in restarting rtorrent with new settings and torrents, so I'm now working on a docker version.
Once done I will return to working on the client itself.
