config/auto/coverage- Check whether coverage analysis tools are present
Coverage analysis is the measurement of the extent to which a program's source code is exercised by its tests.
In Parrot, we can perform coverage analysis on our Parrot source code (well, at least on .c and .pmc files) and on the Perl 5 components used in our tools.
To conduct such analysis, we need the C coverage utility gcov and two utilities, cover and gcov2perl, which are included in the Devel-Cover distribution from CPAN. (Paul Johnson++). This configuration step determines whether those utilities are present.
