To build an executable using this library, use https://gist.github.com/jadonk/a6432fde48408e72fdd7

This builds a library out of a portion of http://processors.wiki.ti.com/index.php/StarterWare. It should also create a tarball that is redistributable, but I need to verify each of the headers to confirm the license really is redistributable.
