http://bitbucket.org/galaxy/galaxy-central/changeset/6937b1a3b3a2/ changeset: r5047:6937b1a3b3a2 user: natefoo date: 2011-02-11 19:12:27 summary: Make loading of job runners dynamic. Changes to lib/galaxy/config.py and lib/galaxy/jobs/__init__.py are no longer required. Existing runners which are not part of the Galaxy source will need to define the class name to instantiate in the __all__ list in the runner. See the included runners for an example. affected #: 7 files (2.2 KB)
