I have put up a new version (v0.3d) of a Perl script that provides Grammar Checking support within LyX's GUI. This version now formats the errors to make them easier to read.
If you are interested in automatically checking your documents for various errors, see: http://wiki.lyx.org/pmwiki.php/Tools/LyX-GrammarChecker If you have any troubles getting it to work, or have any other comments, please email me. It seems be quite simple to use under Linux and MacOSX. I haven't tested it under Windows but it should "just work" if you are using Cygwin. I'd be interested to know if it actually does works with Cygwin. -- John C. McCabe-Dansted Masters Student
