-.SH DESCRIPTION
-Uses Craig Reynolds Boids algorithm to simulate a 3d school of
-fish. See <http://www.red3d.com/cwr/boids> for a description
-of the algorithm and the original paper. This is a lightly modified
-version of the algorithm that supports goal attraction.
-
-Many different behaviors are possible by tweaking the parameters. No sanity checking is performed
-on the command line params, so if you want to use negative accelerations or minimum velocity that is
-larger than maximum velocity or that sort of thing, the simulation will try to digest it.
-
-It looks best with the highest number of fish that will give you an FPS of > 25 or so.
