Just add the inc/ directory to your Module::Build-based file, and then in
Build.PL write something like:
<<<<<<<<<
use File::Spec;
use lib File::Spec->catdir(File::Spec->curdir(), "inc");
use Test::Run::Builder;
my $build = Test::Run::Builder->new(
.
.
.
)
>>>>>>>>>
Then you'll be able to type "./Build runtest" and "./Build distruntest"
to test using Test::Run::CmdLine.
