=head1 NAME
Alien::Build::Plugin::Extract::ArchiveTar - Plugin to extract a tarball using Archive::Tar
=head1 VERSION
version 2.40
=head1 SYNOPSIS
use alienfile;
plugin 'Extract::ArchiveTar' => (
format => 'tar.gz',
);
=head1 DESCRIPTION
Note: in most case you will want to use L<Alien::Build::Plugin::Extract::Negotiate>
instead. It picks the appropriate Extract plugin based on your platform and environment.
In some cases you may need to use this plugin directly instead.
This plugin extracts from an archive in tarball format (optionally compressed by either
gzip or bzip2) using L<Archive::Tar>.
=head1 PROPERTIES
=head2 format
Gives a hint as to the expected format. This helps make sure the prerequisites are set
correctly, since compressed archives require extra Perl modules to be installed.
=head1 METHODS
=head2 handles
Alien::Build::Plugin::Extract::ArchiveTar->handles($ext);
$plugin->handles($ext);
Returns true if the plugin is able to handle the archive of the
given format.
=head2 available
Alien::Build::Plugin::Extract::ArchiveTar->available($ext);
Returns true if the plugin has what it needs right now to extract from the given format
