# This script extracts some data from an OOo bibliographic
# entry. Its command line must contain 2 arguments: the
# file name and the identifier of the biblio entry.
# Note: It's not a real world situation; one should not
# instantiate a document object just for retrieving only
# one element; ooDocument() loads and parses the full
# document, and it's the most costly operation.
