AFAICT ECB is not yet in Emacs.  Maybe it's just a matter of sync'ing
with the upstream CEDET, in which case, I suggest we try and sync ASAP
and then we can remove this entry indeed.

Sounds good.

`undo-tree' is in GNU ELPA, and GNU ELPA packages are kind of half-way
between being part of Emacs and not being part of it (e.g. for copyright
purposes we consider them part of Emacs, i.e. a copyright assignment for
Emacs changes is accepted as covering changes in GNU ELPA).

So some packages in GNU ELPA say "part of Emacs", others say "not part
of Emacs", and I think they're both right and wrong.
