Sorry, I wasn't clear.

You can think of EDE as being broken into some different groups.  There 
is project detection, for finding projects on disk, and there is 'core' 
EDE functionality that just manages file names, menus, keybindings and 
the like.  There are also project implementations, such as a project for 
emacs, linux, and a project type that builds Makefiles for you based on 
meta data you provide.

ede/proj-elisp.el is part of a bigger project that creates Project.ede 
files.  The proj-elisp.el part is for managing Emacs Lisp code in that 
project type, and has code for creating makefile targets.

Anyone who digs into any of the proj-*.el files will find code that 
starts dealing with file name patterns.  These are used for building up 
make rules.  There are some abstractions in there for 'source' files in 
ede/source.el for supporting that.

I suppose that infrastructure could be used to build file patterns based 
on your current target, but it isn't bound to other project types.  I'll 
also guess you won't want EDE dropping Project.ede files or creating 
Makefiles as you go along, so some some development of EDE would be 
needed to start bring the concepts across between the feature sets.

Other project type also have emacs lisp targets, such as the Emacs 
project type.  To use, just enabled ede with

(global-ede-mode 1)

And go edit some Emacs.  Everything you might want to tweak that is 
project specific is in ede/emacs.el

You could also consider

(ede-enable-generic-projects)

to get other basic projects to start being used.  It will track .el 
files, but doesn't have any special features for it.
