DESCRIPTION = """Load a Galaxy model store into a running Galaxy instance.

See the corresponding galaxy-build-objects script for one possible way to
create a model store to use with this script.

This script creates all datasets in "discarded"/"deferred" states (depending on if
source URIs are available). To actually load the datasets into a Galaxy instance's
object store the underlying libraries need to be used directly and fed your Galaxy's
database configuration and objectstore setup.
