Substrate Protocol for User Datagrams (SPUD) Prototype

build.sh does the following

mkdir build     (hold all of the build files in a separate directory)
cd build; cmake (create the makefiles)
make            (To build the code)

You will end up with two test binaries in build/dist/bin, a library you can link against in build/dist/lib.

• build/dist/bin/spudecho is a simple echo-server that echoes back all UDP packets.
• build/dist/bin/spudtest [ipaddr] sends SPUD packets to the desired IP\
• build/dist/bin/spudload [ipaddr] creates many SPUD tubes between this box and the given address

You need to have [cmake](http://www.cmake.org/ to build. Note that version 3.2 or newer is needed. (Some linux distributions are a bit slow to update, so manuall install may be needed.)

Build and run the checks with

make test

If tests fail it can help to run the binaries in build/dist/test to see where they fail.

Travis will compile and run the tests. (https://travis-ci.org/iptube/SPUDlib/)

Coveralls use the coverage.sh script to generate coverage reports. (https://coveralls.io/r/iptube/SPUDlib)

To manually generate lcov reports you can run the ./coveragereport.sh script. A nice html page can be found in lcov/index.html

It can be a bit tricky to get your favorite platform to support gcov and friends, but do not give up! (I had problems on os-x, but unfortunately I do not remember how it was fixed)

TODO: make this more formal.

We like to do C90/C99ish style. Will make sure the library compile on most platforms.

Braces can be placed where you want them. But try to be consistent..

White-spaces when committing should be avoided. (Usual rant on diffs and readability)
