GNU Aspell is a 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.
