What's here:
- auth.py: basic authentication script; used as the basis for authenticating against the ArchivesSpace backend for all of the other scripts here
- marc_export.py: works with our MARC Export plugin to download MARCXML representations of all Resources created or updated after a given time
- update_agents.py: updates authority IDs for Agents to remove the namespace prefix (which we infer from their source)
- update_component_ids.py: does a find/replace on the component ID for all Archival Objects in a Resource tree (ID provided by the user)
