=head1 NAME

Alien::Build::Plugin::Extract::Directory - Plugin to extract a downloaded directory to a build directory

=head1 VERSION

version 2.29

=head1 SYNOPSIS

 use alienfile;
 plugin 'Extract::Directory';

=head1 DESCRIPTION

Some Download or Fetch plugins may produce a directory instead of an archive
file.  This plugin is used to mirror the directory from the Download step
into a fresh directory in the Extract step.  An example of when you might use
this plugin is if you were using the C<git> command in the Download step,
which results in a directory hierarchy.

=head1 PROPERTIES

=head2 format

Should always set to C<d> (for directories).

=head1 METHODS

=head2 handles

 Alien::Build::Plugin::Extract::Directory->handles($ext);
 $plugin->handles($ext);

Returns true if the plugin is able to handle the archive of the
given format.  Only returns true for C<d> (for directory).

=head2 available

 Alien::Build::Plugin::Extract::Directory->available($ext);
 $plugin->available($ext);

Returns true if the plugin can extract the given format with
what is already installed.
