I have installed xemacs a couple of times now, (without the xemacs support package) and as long as I have installed all it's dependencies like compface, libjpeg, libpngl, and zlibl everything went very well.
The xemacs support package size is formidable (over 12 meg). I have been a little apprehensive in letting dpkg uncompress it into something possibly much larger, especially since I am not sure what the benefits would be. Does it contain the above xemacs dependencies? A little more elaboration in the Packages file would help. Thanks, Steve Millard
