Source code for galaxy.metadata.set_metadata
"""
Execute an external process to set_meta() on a provided list of pickled datasets.
This was formerly scripts/set_metadata.py and expects these arguments:
%prog datatypes_conf.xml job_metadata_file metadata_kwds,metadata_out,metadata_results_code,output_filename_override,metadata_override... max_metadata_value_size
Galaxy should be importable on sys.path and output_filename_override should be
set to the path of the dataset on which metadata is being set
(output_filename_override could previously be left empty and the path would be
constructed automatically).
