61 Any number of coverage databases may be specified on the command line.
62 These databases will be merged and the reports will be based on the
63 merged information. If no databases are specified the default database
64 (cover_db) will be used.
65 The -write option will write out the merged database. If no name is
67 given for the new database, the first database read in will be over‐
68 written. When this option is used no reports are generated by default.
69 Specify -select and -ignore options to report on specific files. Spec‐
71 ify -coverage options to report on specific criteria. By default all
72 available information on all criteria in all files will be reported.
73 The -test option will delete the databases and run make test to gener‐
75 ate new coverage data before reporting on it. The -gcov option will
76 try to run gcov on any XS code. This requires that you are using gcc
77 of course. If you are this option will be turned on by default.
