The aspell() functions allows you to check the
spelling on a word and offer suggestions.
����
aspell works only with very old (up to .27.* or so) versions of
aspell library. Neither this module, nor those versions of aspell
library are supported any longer. If you want to use
spell-checking capabilities in PHP, use pspell instead. It uses pspell
library and works with newer versions of aspell.
