Include File Issues

A few problems crept into the version 0.2.0 release. It appears that some include file links were missing, and that a couple of filenames were not in the correct case. These have hopefully been corrected. A new distribution has been posted (the filenames are the same but the dates have been changed).

If you are having problems compiling, and it bombs in the "gravity" sub-library then re-download the distribution and try again.

Please let us know if this does not sort out the problem.
