  Enhanced the SGML filter to also support skipping sgml tags such as "script" blocks.

Silicon Graphics Computer Systems, Inc.
Hewlett-Packard Company
  Parts of the SGI STL code were used in various places throughout the Aspell source.

In addition the authors of some of translated messages did not release their work into the Public Domain, and thus own the copyright to the translated text. See the files `*.po` in the `po` directory for more details.

  The authors of Ispell. Many of the ideas used in Aspell, especially with the affix code, were taken from Ispell. However none of the original Ispell code is used in Aspell.
