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

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.
