Description:

GNU Aspell is a Free and Open Source spell checker designed to
eventually replace Ispell. It can either be used as a library or as an
independent spell checker. Its main feature is that it does a much
better job of coming up with possible suggestions than just about any
other spell checker out there for the English language, including
Ispell and Microsoft Word. It also has many other technical
enhancements over Ispell such as using shared memory for dictionaries
and intelligently handling personal dictionaries when more than one
Aspell process is open at once.
