=head1 NAME

039-run_single_step.t - test C<run_single_step()> during configuration

=head1 SYNOPSIS

    % prove t/configure/039-run_single_step.t

=head1 DESCRIPTION

The files in this directory test functionality used by F<Configure.pl>.

The tests in this file examine what would happen if

This is not its typical or recommended use.  It is more typically called
post-configuration by F<tools/dev/reconfigure.pl>.
