I am ABR. My real name is Adrian Robert. I revived the EmacsOnAqua and created the EmacsApp SourceForge? projects for the port of GNU Emacs to OpenStep? platforms, and helped bring the port into the GNU Emacs mainline in 2008. If you do a configure --with-ns, or if you use AquamacsEmacs version 2+, you’re using this port.
