=head1 NAME
005-run_one_step.t - test Parrot::Configure by running one step
=head1 SYNOPSIS
% prove t/configure/005-run_one_step.t
=head1 DESCRIPTION
The files in this directory test functionality used by F<Configure.pl>.
The tests in this file test those Parrot::Configure methods regularly called
by F<Configure.pl> up to C<Parrot::Configure::runsteps()> but providing only
one step instead of the regular full set.
