PDF Colour Splitter
#!/usr/bin/env python
# Python 2 and 3 compatible.
#This script takes in a PDF and creates two new PDFs. One has the black and
#white pages and the other has the colour pages. It also takes duplex printing
#into account. So a black and white side which is on the same sheet as a colour
#side will be placed into the colour PDF.
#This is from a script created by Iain Murray. The original comment is below.
#This version simply has some different defaults and removes the PDFtoPPM.

'''This script is a "simulation" of an external merge sort in a DBMS. In a DBMS
you will read pages from disk and be able to hold a particular number in
memory. This implementation allows you to set the number of pages by setting
the MAX_BUFFERS variable, and the size of a page by setting the
MAX_BUFFER_SPACE variable.'''
