Please include a copy of the following ``afterthoughts'' with the NBO program documentation. Section A.2 (page A-10): For the GAUSSIAN versions of the NBO program, Read-Write Files 501, 528, 530, 536 and 538 are corrupted by the NBO energetic analysis. This may consequently affect the contents of the checkpoint and archive files. Beware of this if you plan to restart jobs from the checkpoint file or use these files for archival purposes.
