"""
export_to_pdf.py — Scribus Python script: export the current document to PDF.

Intended to be run by proxy_print.py via Scribus in headless mode:
    scribus <document.sla> -g -ns --python-script export_to_pdf.py

The output PDF path is taken from the SCRIBUS_PDF_OUTPUT environment variable.
If not set, it defaults to the same path as the SLA file with a .pdf extension.
