+	* gzip now obeys the principle of least surprise and acts like god intended 
+	    (i.e. it accepts a file name, answers --help, and obeys the '-c' flag 
+	    and only then outputs to stdout).
+	* Fixed more.c to compile autowidth on sparc and set initial winsize 
+	    to 0,0 in case the TIOCGWINSZ ioctl fails.  Fix thanks to Eric Delaunay.
 	* Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
 	* tar now accepts --help
 	* chmod, chown, and chgrp usage now works
-	* General usage cleanups in most apps
+	* General usage (i.e. --help) cleanups for most apps
 	* umount now parses options correctly
+	* tar can now unpack tarballs containing device special files, 
+	    sockets, and fifos (though it can't pack them up) thanks 
+	    to Matt Porter.  Creating archives containing these is still
+	    left to the interested student.
+	* fixed up the license in more.c to properly point to Bruce Perens.
