* New Apps: ping and hostname contributed by Randolph Chung
<tausq@debian.org>. 2 items off the TODO list!
* New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
<tausq@debian.org>. 3 items off the TODO list!
* I wrote free (just calls "cat /proc/meminfo").
* Added tail, based on tail from GNU textutils-1.19, but adjusted
to suit my evil purposes. Costs 6k. I'll make it smaller sometime.
