gcov2perl - convert gcov files to Devel::Cover databases

       Huh?

       Convert gcov files to Devel::Cover databases.

       To obtain coverage of XS files they must first be compiled with the appropriate options.  In a standard
       Makefile environment, such as that created by ExtUtils::MakeMaker, this can be accomplished with the
       command:

        HARNESS_PERL_SWITCHES=-MDevel::Cover make test \
          CCFLAGS=-O0\ -fprofile-arcs\ -ftest-coverage \
          OTHERLDFLAGS=-fprofile-arcs\ -ftest-coverage

       If you have already built your object files it may be necessary to run make clean first, or to find some
       other way to ensure that they get rebuilt with the options gcov requires.

       Now the code coverage data has been collected "gcov" needs to be run:

        gcov Mylib.xs

       This will create one or more gcov files on which you can run "gcov2perl":

        gcov2perl Mylib.xs.gcov

       Finally, "cover" should be run as usual with any options required:

        cover

       If you are running everything with standard options, you can do all this with one command:

        cover -test

       The following exit values are returned:

        0   All files converted successfully
        >0  An error occurred.
