I just grepped my xv-3.00 binary, and found that it invokes /usr/bin/gs
somewhere. A grep for SAFER turned up -- nothing.

Does anyone volunteer to draw up a list of programs that use gs? Here's
a start, off the top of my head:

	* ghostview. 1.4 is vulnerable, 1.5 is not.
	* Web browsers: Mosaic, netscape, etc. Most seem to invoke ghostview
	  directly.
	* metamail.
	* Your postscript printer filter, if you use one.
	* xdvi (v20 is safe)
	* xdvi-k (18f is latest, and still lists -safer in the TODO section).
	* xv (3.0 seems to be vulnerable).
	* xfig. (3.1.3 is safe, don't know about earlier versions).
