  16. Moves a list of remote media from one media store to another.
  17. The input should be a list of media files to be moved, one per line. Each line
  18. should be formatted::
  19. <origin server>|<file id>
  20. This can be extracted from postgres with::
  21. psql --tuples-only -A -c "select media_origin, filesystem_id from
  22. matrix.remote_media_cache where ..."
  23. To use, pipe the above into::
