# [SYNOPSIS](#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](#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.
