Since docopt is not a standard part of Python, nor part of the language 
itself, you may not find anyone here who knows it well enough to solve 
the problem. Also keep in mind that docopt is still a fairly young 
package and may still contain bugs. If we can't help, you should try a 
dedicated docopt mailing list, if any, or try contacting the developer.

I haven't actually used docopt, but I'm willing to try to help...

The defaults for --db and --tb aren't valid Python objects. Perhaps you 
need to specify them as strings?

--db DATABASE   specify database file to use [default: './uwomeds68.db']
--tb TABLE      specify table to use [default: 'matesTb']
