# Usage:
#    tools/warnings.sh [node]
# Output: for each node outputs its warnings and the number of times that
# warning has ocurred. If the argument node is specified, it only shows
# the warnings of that node.
# Examples: tools/warnings.sh
#           tools/warnings.sh 000a
# Environmental variables:
# CHUTNEY_WARNINGS_IGNORE_EXPECTED: set to 1 to filter out expected warnings
# CHUTNEY_WARNINGS_SUMMARY: set to 1 to merge warnings from all instances

# make chutney path absolute
