NAME
       metaclass - a pragma for installing and using Class::MOP metaclasses

VERSION
       version 2.0604

SYNOPSIS
	 package MyClass;

	 # use Class::MOP::Class
	 use metaclass;

	 # ... or use a custom metaclass
	 use metaclass 'MyMetaClass';

	 # ... or use a custom metaclass
	 # and custom attribute and method
	 # metaclasses
	 use metaclass 'MyMetaClass' => (
	     'attribute_metaclass' => 'MyAttributeMetaClass',
	     'method_metaclass'    => 'MyMethodMetaClass',
	 );

	 # ... or just specify custom attribute
	 # and method classes, and Class::MOP::Class
	 # is the assumed metaclass
	 use metaclass (
	     'attribute_metaclass' => 'MyAttributeMetaClass',
	     'method_metaclass'    => 'MyMethodMetaClass',
	 );

	 # if we'd rather not install a 'meta' method, we can do this
	 use metaclass meta_name => undef;
	 # or if we'd like it to have a different name,
	 use metaclass meta_name => 'my_meta';

DESCRIPTION
       This is a pragma to make it easier to use a specific metaclass and a set of custom attribute and method metaclasses. It also installs a
       "meta" method to your class as well, unless "undef" is passed to the "meta_name" option.

       Note that if you are using Moose, you most likely do not want to be using this - look into Moose::Util::MetaRole instead.
