So, they are using optparse. Is there a way to take advantage of this?
When I tried to use the sys.argv=[], I found that having the first option
None gave me a TypeError. If I used:
import sys
sys.argv = ['-stest']
I get this:
Usage: -stest [options]
-stest: error: Please specify a subject ID with '-s'.
Does this make sense to anyone? Same results for sys.argv.extend
I've put the relevant bits of the full trace for the TypeError below (that
was the only time I got a full trace).
