+#!/bin/sh
+# This script can be invoked as a wrapper for an external viewer by lynx, e.g., 
+# given this line in lynx.cfg
+#	XLOADIMAGE_COMMAND:keepviewer xli %s &
+# it will invoke xli on a hardlink to the file (which is assumed to be in the
+# temporary directory created by lynx), and clean up when the viewer exits.
+#
+# Parameters:
+#	$1 is viewer
+#	$2 is filename
+if test $# = 2 ; then
