I like to use tmux in order to keep running sessions on my various hosts for writing code, reading email, etc. I have historically used mosh to connect to these sessions, but recently my place of work has decided that udp is unacceptable. And so I use smux instead.

There are three pieces to this code:

1. tmux-session - a wrapper for tmux that makes it easy to manage 'named' tmux sessions (e.g. code, build, test, log, etc) on a specific host. You can connect multiple times, create a session if it doesn't yet exist, etc.
2. smux - a version of this code that is better suited to work with tmux-session. Connections are kept open with autossh (which is tcp).

So now I can run, say, smux ssiadmin1 code and open a full session, which will re-connect after a network connection goes down.
