[xtext-dev] sf.net CVS down / needed update for de.itemis.xtext.antlr

[Moritz Eysholdt <moritz.eysholdt@xxxxxxxxx>]

Hi,

yesterday I did some small updates to the AntlrGrammar.ext and today the 
sf.net CVS does not allow an CVS update: 
https://sourceforge.net/tracker/index.php?func=detail&aid=2682595&group_id=1&atid=200001

The update is required for Xtext to generate working Antlr based 
parsers. In case you haven't got the update yet, the file is attached.

regards,
 Moritz
