+=head1 NAME
+
+MooseX::StrictConstructor::Meta::Method::Constructor - A meta class to make immutable constructors strict
+
+=head1 SYNOPSIS
+
+ use MooseX::StrictConstructor;
+
+=head1 DESCRIPTION
+
+This class simply overrides C<_generate_BUILDALL()> in
+C<Moose::Meta::Method::Constructor> so that classes that are made
+immutable have a strict constructor.
+
+You should never have to use this class directly.
