Please create a jira for such changes and use that JBIDE id in the 
commit - makes life much easier ;)
    

Right, of course.  Sorry.

See https://jira.jboss.org/jira/browse/JBIDE-3557.  Comments/advice
welcomed!
  

Also, if anyone is interested, I could write up how to build and test
the pseudo-langpacks for JBoss Tools.
   
      

Please do - put it on our wiki!  www.jboss.org/tools
    

I've made a start here: http://www.jboss.org/community/docs/DOC-13256
