       Dpkg::BuildFlags - query build flags


       The Dpkg::BuildFlags object is used by dpkg-buildflags and can be used
       to query the same information.


       my $bf = Dpkg::BuildFlags->new()
           Create a new Dpkg::BuildFlags object. It will be initialized based

           Reset the flags stored to the default set provided by the vendor.

           load_environment_config() to update the default build flags defined
           by the vendor.

       $bf->set($flag, $value, $source)
           Update the build flag $flag with value $value and record its origin
           as $source.

       $bf->append($flag, $value, $source)
           Append the options listed in $value to the current value of the
           flag $flag.  Record its origin as $source.

       $bf->update_from_conffile($file, $source)
           Update the current build flags based on the configuration
           directives contained in $file. See dpkg-buildflags(1) for the
