Kepler

ant -p says:

run Compile, then run Kepler along with the modules in modules.txt. Use -Dworkflow=model.xml to run a model.

When I run:
ant run -Dworkflow=${HOME}/Downloads/SimpleLoop.kar

I get

[run] RunClasspath:ptolemy /Users/cxh/src/kepler/ptolemy/src

In addition, the process hangs and I have to type control-c.

This makes it annoying to use Kepler to check out bugs and open models.

ant run -Dworkflow=SimpleLoop.kar
also fails.

Basically, it looks like -Dworkflow does not work?
