-You are reading this file because you want to build a new copy of the LwIP library for
-use in ZeroTier.
-
-Subdirectories:
-
- ports/ -- contains ports for various architectures (for our purposes, unix)
-
-In order for the Network Containers feature to work in ZeroTier, a copy of the LwIP libary
-is needed since we dynamically load it into memory. You can build a new copy of the libary 
-by going to /contrib/ports/unix/proj/lib and running make.
-
-This will generate: liblwip.so
-
-You can enable LwIP debug traces by adding the flag -DLWIP_DEBUG
-See additional debug info here: http://lwip.wikia.com/wiki/Debugging_lwIP

-This directory contains an example of how to compile lwIP as a self
-initialising shared library on Linux.
-
-Some brief instructions:
- 
-* Compile the code:
-
- > make clean all
-
- This should produce liblwip4unixlib.so.  This is the shared library.
-
-* Link an application against the shared library
-
- If you're using gcc you can do this by including -llwip4unixlib in
-your link command. 
-
-* Run your application
- 
- Ensure that LD_LIBRARY_PATH includes the directory that contains
-liblwip4unixlib.so (ie. this directory)
-
-
-
-If you are unsure about shared libraries and libraries on linux in
-general, you might find this HOWTO useful:

-<http://www.tldp.org/HOWTO/Program-Library-HOWTO/>
