This is the C version of the new layman API. To use it, you must first get the new Layman API : git clone http://dev.gentooexperimental.org/~dol-sen/git/layman.git Then, type ./configure make After that, you can compile and run the tester with ./run-test.sh Note that it's still in an unstable state, try to always use the latest git version of this library and of the new Layman API.
