+=head1 NAME
+
+MooseX::Getopt::Parser::Descriptive - A Getopt::Long::Descriptive parser for MooseX::Getopt
+
+=head1 SYNOPSIS
+
+  use MooseX::Getopt::Parser::Descriptive;
+
+  my $parser = MooseX::Getopt::Parser::Descriptive->new(
+      format => 'Usage: %c %o',
+      config => ['pass_through']
+  );
+  my $getopt = MooseX::Getopt::Session->new( parser => $parser );
+  my $app = My::App->new( getopt => $getopt );
+
+=head1 DESCRIPTION
+
+This class does L<MooseX::Getopt::Parser> for L<MooseX::Getopt>.  This
+class is used by default if L<Getopt::Long::Descriptive> module is
+missing.
+
+=head1 METHODS
+

+
+=item B<build_options ($getopt, @attrs)>
+
+This method parses the CLI options with L<Getopt::Long> and returns a hashref to options list.

+The first argument have to be L<MooseX::Getopt::Session> object and
+second argument is a list of attributes which contains options.
+
+=item B<config>
+
+This accessor contains the arrayref to list with special configuration
+keywords for L<Getopt::Long>.
