My git repository has serious issues, trying to resolve. Apologies for tag pollution here but the drupal.org infrastructure is failing but without errors so I cannot debug without creating new tagged releases here. Attempting to delete and recreate pushtape_core directory.
This is the first working snapshot of pushtape_features. It is not entirely stable, but drupal-org.make will not let you include dev releases of modules, so this is a stop gap solution to test the pushtape install profile.
