molecules are contained in the {\sc Kernel} which is |

implemented with {\sc Base Classes} and are carefully designed to |

provide maximum extensibility and flexibility. The functionality |

required for applications is provided by the third layer which |

handling, but also defines a generic force field interface. Another |
| 51 |

important component of Input/Output module is the parser for |

The Molecular Mechanics module consists of energy minimization and a |

wide variety of integration methods(see |
