Hi Andreas!
Sorry for not showing activity, I've experienced some strange technical troubles
with my VM :( It turned out that switching to unstable in sources.list
is not enough to work well with cme and testing packages from unstable,
now I fixed it (switched to virtual box with unstable Debian on it).
I've added test for checking result files and another call with non-default parameter set from readme (I decided not to move it to separate file because these two calls look almost the same, although setting up some additional parameters can change output file appearance. One of probable things worth testing is pymol script produced by concavity, it can reveal that file's compartibility with specific version of pymol, but it seems to be redundant, and on my display-less VM I was not able to call it without errors with xvfb, at least for now).
