I'm quite new to Oz too, but I can hazard a guess why "ozecho --foo"
gives an error and "ozecho foo" doesn't.
My guess would be that you haven't defined "foo" in the Spec that you
pass to Application.getArgs. This is an error, so Application.getArgs
throws the exception that you see as "unknown option 'foo'". See "Error
Handling" in http://www.mozart-oz.org/documentation/system/node2.html
for more info.
