attach processes running on other terminals

 retty is a tiny tool that lets you attach processes running on other
 terminals. So you were running that mutt outside of screen at your home
 machine and now wanna check your mail? Attach it with retty, do whatever you
 want, detach it again and everything is as it was before. You don't have to
 run them all in screen just in case.
 .
 Note that the tool is only very lightly tested, so take some care. Always
 check first if attaching given application works before you will do it for
 real.
