Others too numerous to mention have reported and fixed bugs, and added
features to many parts of Emacs.  We thank them for their generosity as
well.

This list intended to mention every contributor of a major package or
feature we currently distribute; if you know of someone we have omitted,
please report that as a manual bug.
