=head1 SYNOPSIS

use alienfile;
 plugin 'PkgConfig' => (
   pkg_name => 'libfoo',

the best C<PkgConfig> plugin depending your platform and environment.

=head1 PROPERTIES

=head2 pkg_name

The package name.  If this is a list reference then .pc files with all those package
names must be present.  The first name will be the primary and used by default once
installed.  For the subsequent C<.pc> files you can use the
L<Alien::Base alt method|Alien::Base/alt> to retrieve the alternate configurations
once the L<Alien> is installed.

=head2 atleast_version

The minimum required version that is acceptable version as provided by the system.

=head2 exact_version

The exact required version that is acceptable version as provided by the system.

=head2 max_version

The max required version that is acceptable version as provided by the system.

=head2 minimum_version

Alias for C<atleast_version> for backward compatibility.

=head1 METHODS

=head2 pick

my $name = Alien::Build::Plugin::PkgConfig::Negotiate->pick;

Returns the name of the negotiated plugin.

=head1 ENVIRONMENT

=over 4

=item ALIEN_BUILD_PKG_CONFIG

which attempts to automatically pick the best plugin.
