#!/usr/bin/python

# This script removes branch and/or line coverage data for lines that
# contain a particular substring.
#
# In the interest of "fairness" it removes all branch or coverage data
# when a match is found -- not just negative data.  It is therefore
# likely that running this script will actually reduce the total number
# of lines and branches that are marked as covered (in absolute terms).
#
# This script intentionally avoids checking for errors.  Any exceptions
# will trigger make to fail.
