=head1 SYNOPSIS

 use alienfile;
 plugin 'Extract' => (

This is a negotiator plugin for extracting packages downloaded from the internet. 
This plugin picks the best Extract plugin to do the actual work.  Which plugins are
picked depend on the properties you specify, your platform and environment.  It is
usually preferable to use a negotiator plugin rather than using a specific Extract
Plugin from your L<alienfile>.

=head1 PROPERTIES

C<tar>, C<tar.gz>, C<tar.bz2>, C<tar.xz>, C<zip>, C<d>.
