This directory contains the operating system port and some example files
for the lightweight TCP/IP stack (lwIP). You can download the stack sources
at the project homepage  http://savannah.nongnu.org/projects/lwip/

Installation:

  -  Extract the source tar ball into this directory, so that you get a
     subdirectory named lwip-x.x.x  (the x's are the version number).
     Example:  /contrib/network/tcpip/lwip-1.1.1

  -  Edit the file lwip_cfg.mak. There is a variable that must point to
     the lwip directory.  Example: LWIP = lwip-1.1.1

Now you are able to compile the example program "chargenloop" in the
examples subdirectory. Please change into the directory

  /contrib/network/tcpip/examples/chargenloop

and type "make PORT=x86w32" or whatever your target platform port is.
For the MS Windows port you only need to install the MinGW compiler
for MS Windows (you can download the compiler at
 http://mingw.sourceforge.net/download.shtml ).

For your own projects, you will need the configuration file "lwipopts.h".
You can use the file in the chargenloop example as template, or you
can use the file lwip-x.x.x/src/include/lwip/opt.h as example.
You may store the lwip configuration file in the same directory where
your picoos configuration files are stored.
