       Report coverage statistics in a variety of formats.

       The summary option produces a short textual summary.  Other reports are available by using

       The following reports are currently available:

        text                  - detailed textual summary
        html                  - detailed HTML reports

        other options specific to the report


       Any number of coverage databases may be specified on the command line.  These databases
       will be merged and the reports will be based on the merged information.  If no databases
       are specified the default database (cover_db) will be used.

       The -write option will write out the merged database.  If no name is given for the new
       database, the first database read in will be overwritten.  When this option is used no
       reports are generated by default.

       Specify -select and -ignore options to report on specific files.  Specify -coverage
       options to report on specific criteria.  By default all available information on all
       criteria in all files will be reported.

       The -test option will delete the databases and run make test to generate new coverage data
       before reporting on it.  The -gcov option will try to run gcov on any XS code.  This
       requires that you are using gcc of course.  If you are this option will be turned on by


       The following exit values are returned:

       0   All operations were completed successfully.
