+`tty-fwd` is a utility to capture TTY sessions and forward them. It spawns processes in a pseudo-TTY and records their output in asciinema format while providing remote control capabilities.
 
-`tty-spawn` is the underlying library on which
-[`teetty`](https://github.com/mitsuhiko/teetty) is built.  It lets you spawn
-processes in a fake TTY and duplex stdin/stdout so you can communicate with an
-otherwise user attended process.
