Things to notice

• The current QM/MM implementation in ADF is limited to a total of 1000 QMMM atoms;
  currently, a new implementation is underway that is more flexible, and that doesn't have this limit.
  It will be available within the near future.
• The pdb2adf program uses AMBER parameter files, and is setup to work with the AMBER force field,
  version AMBER95, which is designed for and works well for biosystems.
