Pspell
The purpose of Pspell was to provide a generic interface to the system spelling checking libraries. It was, and sometimes still is, used in computer programming such as C, and is licensed under the GNU Lesser General Public License.
Pspell has not been updated since 2001, but is still available on SourceForge at . It has been replaced by GNU Aspell. PHP’s Pspell extension, while retaining its current name, now uses the Aspell library.
