Converts every scribus document to a PDF in a specified directory.

"""
Convert every .sla to a pdf in a specified directory.

import os

work_dir = #you have to explicitly tell scribus where your working directory is.
filenames = os.listdir(work_dir)

for filename in filenames:
    if filename.endswith(".sla"):
        full_path = os.path.join(work_dir, filename)
        filename_root = os.path.splitext(filename)[0]
        filename_pdf = os.path.join(work_dir, filename_root+".pdf")
        
        openDoc(full_path)
        pdf = PDFfile()
        pdf.file = filename_pdf
        pdf.save()
        closeDoc()

For any others finding this, I've implemented a somewhat more sophisticated command-line and Python API wrapper for Scribus PDF export: https://github.com/sla2pdf-team/sla2pdf
