/*! \mainpage Fracplanet : fractal terrain generator

  \author Tim Day

  \section introduction Introduction
  "Fracplanet" is an interactive tool for generating fractal planets and terrains.
  It can output the generated meshes to files suitable for use by POV-Ray.

  \todo For new features to be added, see the TODO file.
