Has this been abandoned?

This won’t install on a clean WP 3.8 install. It generates this error:

The package could not be installed. The theme is missing the <code>style.css</code> stylesheet

There’s no indication on the scholarpress.org site that the plugin is still being maintained, and no updates here for over two years.

Does anyone know if the developers have abandoned this, or if anyone has picked it up?
