There seem to be two source directories

[jockm]

There seem to me two source directors source and ugui. What is the relationship between these two directories?

source is for c sources, ugui is for headers. Usually I put them both under a lib directory, but the mbed build tools didn't like it so here we are...

The reason it's ugui instead of include is so that if the library were installed the include path is ugui/whatever.h and the library should also use that internally / still work.
