## NAME
    gcov2perl - convert gcov files to [Devel::Cover] databases

## VERSION
    version 1.36

## SYNOPSIS
     gcov2perl -h -i -v -db database gcov_files

## DESCRIPTION
    Convert gcov files to [Devel::Cover] databases.

## OPTIONS
    The following command line options are supported:

     -db database    - specify the database to use

     -h -help        - show help
     -i -info        - show documentation
     -v -version     - show version

## DETAILS
    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

## EXIT STATUS
    The following exit values are returned:

     0   All files converted successfully
     >0  An error occurred.
