I would like to take this up as a project. I have played with the idea
of a spell checker for the apropos(1) project (even implemented one,
although quite a naive implementation). I would like to take this
opportunity to come up with a more sophisticated implementation of the
spell checker and implementing it in the form of a library so that
other utilities (like apropos(1)) may also benefit from it.
