# This is the uploader. It simplifies the testing process immensely and  makes
# autoILIAS finally obsolete, since this system uses a proper Ilias
# implementation.
#
# The code is straight forward. You need to seed s couple of POST requests
# in the right order an then the items appear at the right place. Currently
# works for the Folder 'Sandkasten' of the test environment that ships
# with hallgrim. Ilias changes often so maybe the urls have to be updated.
#
# The simplest way was to intercept the html traffic with wireshark.
#
# Sadly this script adds some ugly dependencies like requests_toolbelt.
