# Description:
#
# This script can be used as a notification script for a Helios Create PDF
# printer queue. It's aim is to split a newly created PDF into single pages.
# To do this, it creates a subfolder within the queue's target folder and 
# stores the single page PDFs inside.
#
# Currently it works only with ES 3.1 (due to the format of parameters
# supplied by the EtherShare printer queue and paths to the utilities)
#
#############################################################################
#
# TODO:
# 
# Ensure, that while renaming no PDFs will be created with names longer 
# than 31 chars to avoid visibility problems for mac clients (It's a known
# limitation of AFP < 3.x that filenames must not be longer than 31 bytes)
