graxxia is now in NEW, it took me 1 hour to package it. I packaged the latest version available in the Github repository (commit 85b386e), this version doesn't match the jar released in Maven Central under the version 1.0.1 because the repository is missing the Bars class. I suspect the Git repository is between the versions 0.9 and 1.0, so I used the version 1.0~20150714 for the package. Emmanuel Bourg
