=head1 NAME
Lintian::Processable::Source::Components - interface to orig tar components
=head1 SYNOPSIS
use Moo;
with 'Lintian::Processable::Source::Components';
=head1 DESCRIPTION
Lintian::Processable::Source::Components provides an interface to data for
upstream source components. Most sources only use one tarball.
=head1 INSTANCE METHODS
=over 4
=item components
Returns a reference to a hash containing information about source components
listed in the .dsc file. The key is the filename, and the value is the name
of the component.

# even when this would be a tarball.
