Yeah I think a separate terminal emulator library would be useful to have. I 
had started to write one as an ocaml-vnc example â the initial idea was to 
replace a common Xen tool called âvnctermâ â but I ran out of time on that 
particular project. I was also wondering what it would take to build something 
like tmux.

The example terminal code in that repo is probably not worth the bother of 
examining too closely.

Dave
