#!/usr/bin/python
#
# This program 'pretty prints' the ctest output, namely
# files from builddir/Testing/Temporary. 
# html & wiki output are produced in Testing/Temporary/wiki
# wiki uploading is available by running 
# 
#  python test_pretty_print.py --upload

# todo
# do something if tests for opencsg extensions fail (fail, no image production)
# copy all images, sysinfo.txt to bundle for html/upload (images 
#  can be altered  by subsequent runs)
# figure out hwo to make the thing run after the test
# figure out how CTEST treats the logfiles.
# why is hash differing
# instead of having special '-info' prerun, put it as yet-another-test
#  and parse the log
