File manager / Makefile generator for Emacsen
EDE is a project management system. It implements projects under
Emacsen making it easy to maintain programs without learning
make.

EDE is now a part of CEDET (Collection of Emacs Development
Environment Tools).
You'll have to build Equinox Desktop Environment from source (the site has instructions). If you DO have a source post it please.
