[kepler-dev] RE : RE : [kepler-users] matlab expression problem

[Matthew Jones]

You can recompile if you are using a version checked out from CVS by 
using the provided ant 'run-dev' task.  See the documentation about how 
to build and run Kepler on the wiki (http://kepler-project.org).

If you have located a bug or limitation in the ExecuteCommand actor, 
could you please summarize the changes needed to fix it on windows 2003, 
and if possible post a patch to the kepler-dev list?  Thanks.
Matt
