The program pack is a replacement for the install program that make it possible to uninstall etc. Use it if you are compiling your software by yourself (like me). (If you install building E and GNOME by your self this is a perfect way to easy be able to uninstall old version before installing a new version) http://www.linuxos.org/Pack.html [NOTE of the LTT maintainer : like written on the above page, the author of Pack has stopped its development, because he's found something better, called Encap, available here : http://encap.cso.uiuc.edu/encap ]
