removeOldFiles.py

# This script is used to clean the cookbook from the old empty cockles that 
# should not be shipped with the product anymore. 
#
# It will search for a file named 'fileList.txt' in the current directory, and parse it.
# This file should contain the list of empty cockles to keep, in the following form:
#   Plants/Grasses - Plants|http://cornucopia3d.e-oncontent.com/storeItems/Plants/Grasses - Plants/RA_Weeds__Fields_and_Meadows_01_tpf_25_~~.tpf|20160506
# That is, 'folder|url|date'. The name of the file is mainly given by the url. The date is unused by this script.
#
# It will also ask you to give it the path to the input folder, which should be the root of the 
# cookbook repository. For example, "/c/work/cookbook", or just "./cookbook" (without the quotes, of course).
