	# Applescript to batch OCR PDFs using PDF Expert.
	# By Alex Wellerstein. Last updated March 14, 2024. No copyright asserted -- released for public domain use.
	# Absolutely no warranties, guarantees, promises, ANYTHING provided. Use at your own risk.
	# This is NOT affiliated with PDF Expert or Readdle in any way.
	#
	# Will automatically save and close each PDF after OCR completes.
	# Assumes PDF Expert is the default program to open PDFs!
	# Does not have robust error handling. Held together with duct tape.
	# Just a temporary solution until Readdle builds in actual automation support (one can dream...).
	# Seems to work on OS 14.3.1, with PDF Expert 3.9.2.
