I actually did that, several times.
My mistake was that I didn't realize I was supposed to have Drake.jar in the same folder as the workflow that I was trying to execute (I'd keep getting the error 'Unable to access jarfile drake.jar'). Naive error, I suppose.
However, I'm still having trouble executing the 'A nicer way to run Drake' instructions. I created a file named 'drake' on my path, and inserted the given text. However, I keep getting the error
'Exception in thread "main" java.lang.NoClassDefFoundError: drake/core'
Was I supposed to alter the script in any way? I just naively copy/pasted.
