      LCOV is an extension of GCOV, a GNU tool which provides information
      about what parts of a program are actually executed (i.e.,
      "covered") while running a particular test case.  The extension
      consists of a set of PERL scripts which build on the textual GCOV
      output to implement the following enhanced functionality such as
      HTML output.
