#### make-bin-dist: create a binary Emacs distribution tar file for
#### Mac OS X.  This basically runs a `configure' and `make install'
#### into a temporary directory and archives that directory.  It also
#### places the Emacs application bundle and a installer script in the
#### tar file.  The installer script is run to set up the XML file for
#### setting the environment variables used by Emacs when it is
#### started from the Finder.
