+ <h1>lwIP - A Lightweight TCP/IP Stack</h1>
+ <p>
+ The web page you are watching was served by a simple web
+ server running on top of the lightweight TCP/IP stack <a
+ href="http://www.sics.se/~adam/lwip/">lwIP</a>.
+ </p>
+ <p>
+ lwIP is an open source implementation of the TCP/IP
+ protocol suite that was originally written by <a
+ href="http://www.sics.se/~adam/lwip/">Adam Dunkels
+ of the Swedish Institute of Computer Science</a> but now is
+ being actively developed by a team of developers
+ distributed world-wide. Since it's release, lwIP has
+ spurred a lot of interest and has been ported to several
+ platforms and operating systems. lwIP can be used either
+ with or without an underlying OS.
+ </p>
+ <p>
+ The focus of the lwIP TCP/IP implementation is to reduce
+ the RAM usage while still having a full scale TCP. This
+ makes lwIP suitable for use in embedded systems with tens
+ of kilobytes of free RAM and room for around 40 kilobytes
+ of code ROM.
+ </p>
+ <p>
+ More information about lwIP can be found at the lwIP
+ homepage at <a
+ href="http://savannah.nongnu.org/projects/lwip/">http://savannah.nongnu.org/projects/lwip/</a>
+ or at the lwIP wiki at <a
+ href="http://lwip.wikia.com/">http://lwip.wikia.com/</a>.
