# This script will check anaconda for any pylint warning and errors using a set
# of options minimizing false positives, in combination with filtering of any
# warning regularexpressions listed in pylint-false-positives.
# 
# If any warnings our found they will be stored in pylint-log and printed
# to stdout and this script will exit with a status of 1, if no (non filtered)
# warnings are found it exits with a status of 0
