       OVERVIEW: Sanitizer Coverage Processing Tool (sancov)

              This    tool    can    extract    various    coverage-related   information   from:
              coverage-instrumented binary files, raw .sancov files and their symbolized  .symcov
              version.  Depending on chosen action the tool expects different input files:

       -print-coverage-pcs     - coverage-instrumented binary files

       -print-coverage         - .sancov files

       <other actions>
              - .sancov files & corresponding binary files, .symcov files
