README's for apps?

[markus <ma...@bibi.ca>]

it seems iptest is the only app that uses the/an ethernet port, which
is great, except that I can't figure out what the app does or should
do. Or maybe I should say what I'm supposed to do.

It's simple enough to figure out what blinky does, and after a while
you get what pwm_test does. iptest seems to expect me to type sensical
commands into the console - which I'm afraid is far beyond my
expertise.

So I was wondering if it would make sense to add a README to all apps
in the mynewt-core repository with an overview of what the app does,
how it's supposed to be used, maybe with example.

Much appreciated if anybody has a pointer or so.

Thanks a bunch,
Markus
