The engine of this spell checker is based on the jazzy spell checker developed by Mindaugas Idzelis, Robert Gustavsson, and Jason Height. The jazzy project is hosted on Sourceforge.net: http://www.sourceforge.net/projects/jazzy.
Bodo Tasche informed me about the new jazzy facilities hidden in the jazzy
CVS and about the dictionaries at http://www.sf.net/projects/jaxe.
