Alien::Build::Plugin::Extract::Negotiate - Extraction negotiation plugin

=head1 VERSION

version 1.42

=head1 SYNOPSIS

 use alienfile;
 plugin 'Extract' => (
   format => 'tar.gz',

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

=head2 format

The expected format for the download.  Possible values include:
C<tar>, C<tar.gz>, C<tar.bz2>, C<tar.xz>, C<zip>, C<d>.

=head1 METHODS

=head2 pick

 my $name = Alien::Build::Plugin::Extract::Negotiate->pick($format);

Returns the name of the best plugin for the given format.
