-"""
-NB: adapted to work as a library for PDF extraction. Will probably be
-re-written eventually to be correct, complete, and robust; this is just a
-first iteration.
-
-This script tries to extract everything from a GROBID TEI XML fulltext dump:
-
-- header metadata
-- affiliations
-- references (with context)
-- abstract
-- fulltext
-- tables, figures, equations
-
-A flag can be specified to disable copyright encumbered bits (--no-emcumbered):
-
-- abstract
-- fulltext
-- tables, figures, equations
-
-Prints JSON to stdout, errors to stderr

-This file copied from the sandcrawler repository.
