Martin, welcome.
My progress has not been in progress these days because of the
business trip.
I've added following items to HACKING file.
Developers
==========
Xtla will be merged to GNU Emacs(we hope).
So the developers should be able to sign to FSF about
copyright transfer. [FIX ME THIS ENGLISH]
Menu item conventions
=====================
- Each Nouns and verbs in menu items are should be capitalized.
David PONCE, the tree-widget.el's author got the write-access to
emacs CVS repository. So tree-widget.el will be part of GNU Emacs
in soon.
