Ok. It could be added, so symref-grep can use it. find-file could also
use it.

A single Project.ede for each project is fine, as long as it tells me
that it's being created, and where. I expect a project manager to need a
project definition file.

Makefiles are not fine; many projects have no need of Makefiles (they
use other build tools). An explicit command to create a Makefile (or
other build specification file) would be fine.

Right. I'm willing to help do that development.

Is that supposed to work for random elisp code, or only for code in the
core Emacs repository?

I don't see any effect in random elisp code; in particular, M-:
(ede-current-project) returns nil.

Testing; same result in emacs/master/lisp/xml.el.

So I'm missing something.

Hmm. No mention of load-path, so no tools for setting it. And some of
the functions are specific to the Emacs repository, but others are fully
general (ede-emacs-find-in-directories).

I had found that; still gives nil for (ede-current-project) in a .el
file, even after I did M-x ede-new, which created a Project.ede (without
telling me the file name or location) and an entry in my ~/.emacs
Customize (again without telling me).

I did some digging; it seems I didn't create a target. But Development |
Target Options | New Target is greyed out. It seems I created an
Automake project (it was the only choice even after
ede-enable-generic-projects), and that doesn't support creating targets.

Still missing something.
