Style and grammar checker. LGPL

LanguageTool 0.9 is a style and grammar checker that currently supports English, German, Polish, and Dutch, and offers initial support for other languages like French and Spanish. It scans the words and their part-of-speech tags for occurrences of error patterns, which are defined in an XML file. Furthermore, more powerful error rules can be written in Java. LanguageTool should be used after the spelling of a text has been corrected.
