XEmacs Wrapper is a wrapper around the excellent XEmacs editor, which you will need to install via fink (into /sw/bin) or by compiling the source (into /usr/local/bin).
This wrapper integrates XEmacs into the Finder by providing a regular double-clickable application that will activate X11 and launch XEmacs. Of course, it completely supports drag-and-drop, too! Also, I enlarged and enhanced one of the classic XEmacs icons, so the Finder icon for this wrapper looks nice at 128x128.
You will need to install XEmacs:
by compiling the source (installs into /usr/local/bin), or by using fink (installs into /sw/bin), or by using DarwinPorts (installs into /opt/local/bin)
