"""bulk_export_pdf.py
Bulk convert a selection of Scribus files to PDF with the built-in
export preferences. This script must be run from inside scribus with
the Scripts->Execute feature.

Note: This script requires PyQt5, since Scripter does not have (AFAIK)
a built in dialog to select multiple files.
