Q.  What are the open source spell checkers?

A.  Its confusing.  If you search, you'll find there are large number of
open source spell checkers.  But there's the simple answer:

spell		The first spell checker.  It was built into Unix.
		Simply listed misspelt words.
		
ispell		International Spell checker.  Gave line numbers where the
		mistake was and suggestions.  Dictionaries for multiple
		languages.

aspell		Better spell English suggestions that ispell.  Can
		emulate ispell so was a drop-in replacement.
		Also had dictionaries for multiple languages.
		But only Western languages was was ASCII-based.
		For now, this is the king.  Dictionaries for many
		languages available as packages for Fedora/RedHat/CentOS.

dspell		Dave Spell.
		I made this as a programming experiment.  A drop in replacement
		for ispell or aspell.   Suggestions are almost certainly
		as good as aspell but it basically works and has
		very minimal dependencies so easy to compile.

hunspell	Hungarian spell checker.  Supports Unicode and
		all languages.  This appears to be the rising star.
		Already the default spell checker of OpenOffice.org,
		Firefox and Thunderbird.
