Tiny login manager.
This is a login manager designed to be as small (in lines of code) as possible, for flexbility and extensibility. Uses charm libraries for visuals. I'm not currently sure how to implement it as an actual login manager (à la GDM, XDM) but currently it can be used as e.g. a lock screen.
tlm uses PAM with the login context for user authentication. Therefore it should work on any device that uses PAM and has a PAM service configuration for login.
