Test::Lintian::Build -- routines to prepare the work directories
=head1 SYNOPSIS
use Test::Lintian::Build qw(build_subject);
=head1 DESCRIPTION
The routines in this module prepare the work directories in which the
tests are run. To do so, they use the specifications in the test set.

in SPEC_PATH. The optional parameter REBUILD forces a rebuild if true.
