Like setting the test paths? I was kinda anoyed that I had to specify them. Did you also build in a way to leave the tests out?

in hem version0_3 branch you can leave out tests if I remember right, been a bit since I worked on that.

the example app is way out of date and the test paths are probably way off because of that. we need to update spine.app to build out apps that are already all laid out with test stuff set up better. that actually needs to preceed updating this example app. we are partially done with that work, but probably going to skip updating the example app in the hem0.2 vein.
