# 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.
