=head1 NAME

Lintian::Processable::IsNonFree - Lintian interface to source package data collection

=head1 SYNOPSIS

    my ($name, $type, $dir) = ('foobar', 'source', '/path/to/lab-entry');
    my $collect = Lintian::Processable::IsNonFree->new($name);
    if ($collect->native) {
        print encode_utf8("Package is native\n");
    }

=head1 DESCRIPTION

Lintian::Processable::IsNonFree provides an interface to package data for source
packages.  It implements data collection methods specific to source
packages.

This module is in its infancy.  Most of Lintian still reads all data from
files in the laboratory whenever that data is needed and generates that
data via collect scripts.  The goal is to eventually access all data about
source packages via this module so that the module can cache data where
appropriate and possibly retire collect scripts in favor of caching that
data in memory.

=head1 INSTANCE METHODS

=over 4

=item is_non_free

Returns a truth value if the package appears to be non-free (based on
the section field; "non-free/*" and "restricted/*")
