 	    patch your kernel with the devps patch in the kernel-patches/
 	    directory. 
 	* Wrote basename, killall, and uptime.
+	* tar has been completely rewritten by me.  Both tar creation and 
+	    extraction are now well behaved.  Costs 7.6k with all optional
+	    tar features enabled, and 5k for just tar extraction support. 
 	* Added freeramdisk, which will free up all memory associated
 	    with a ram disk.  Contributed by Emanuele Caratti <wiz@iol.it>
 	    and then adjusted a bit by me.
 	* Added tr and dirname from John Lombardo <john@deltanet.com> 
 	* Added echo and test (from me).
 	* Added usleep contributed by Nicolas Pitre <nico@cam.org>
-	* tar wouldn't create directory entries that don't end in '/',
-	    now it does (thanks to Avery Pennarun <apenwarr@worldvisions.ca>)
-	* tar has been completely rewritten, and tar creation and extraction
-	    is now much better behaved.
 	* Several fixes from Pavel Roskin <pavel_roskin@geocities.com>:
 	    -  When `tail' fails to open a file it now exits.
 	    - When `syslogd' is given the `-n' option it should still use
