Package: wnpp
Severity: wishlist
Owner: Christoph Berg <myon@debian.org>

* Package name : retty
Version : 1.0
Upstream Author : Petr Baudis, Jan Sembera
* URL : http://pasky.or.cz/~pasky/dev/retty/
* License : GPL
Programming Lang: C and i386 asm (it doesn't work on amd64)
Description : lets you 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.

We send SIGWINCHs around to make the applications recheck window
dimensions and redraw the screen - if they don't, try pressing Ctrl-L.

To anyone else who was curious about this:

What it seems to be doing is injecting code onto the stack which causes
the target process to open your terminal and dup2 it onto stdout,
stderr, et cetera. Interesting.
