This is a patch file for "xearth" 1.1. This patch adds support for the
"q", "Q",  and/or  Escape keys to  XEarth  [but only for X11 "-noroot"
mode].  If you run the program in X11 "-noroot" mode and press  one of
these keys,  the program should exit in about one second [or  slightly
less].

This file should be compatible with all distros that support the orig-
inal program.
