uIP is a very small implementation of the TCP/IP stack that is written
by Adam Dunkels <adam@sics.se>. More information can be obtained
at the uIP homepage at http://www.sics.se/~adam/uip/.
This is version $Name: uip-1-0 $.
The directory structure look as follows:
apps/ - Example applications
doc/ - Documentation
lib/ - Library code used by some applications
uip/ - uIP TCP/IP stack code
unix/ - uIP as a user space process under FreeBSD or Linux
This directory contains a few example applications. They are not all
heavily tested, however.
