=head1 NAME

Alien::Build::Plugin::PkgConfig::CommandLine - Probe system and determine library or tool properties using the pkg-config command line interface

=head1 VERSION

version 2.84

=head1 SYNOPSIS

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

=head1 DESCRIPTION

Note: in most case you will want to use L<Alien::Build::Plugin::PkgConfig::Negotiate>
instead.  It picks the appropriate fetch plugin based on your platform and environment.
In some cases you may need to use this plugin directly instead.

This plugin provides Probe and Gather steps for pkg-config based packages.  It uses
the best command line tools to accomplish this task.

L<Alien::Base alt method|Alien::Base/alt> to retrieve the alternate configurations
once the L<Alien> is installed.

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

=head2 exact_version
