=head1 NAME
Moose::Meta::Method::Augmented - A Moose Method metaclass for augmented methods
=head1 DESCRIPTION
This class implements method augmentation logic for the L<Moose>
C<augment> keyword.
The augmentation subroutine reference will be invoked explicitly using
the C<inner> keyword from the parent class's method definition.
=head1 INHERITANCE
C<Moose::Meta::Method::Augmented> is a subclass of L<Moose::Meta::Method>.
=head1 METHODS
=over 4
=item B<< Moose::Meta::Method::Augmented->new(%options) >>
This constructs a new object. It accepts the following options:
=over 8
=item * class
The metaclass object for the class in which the augmentation is being
declared. This option is required.
=item * name
The name of the method which we are augmenting. This method must exist
in one of the class's superclasses. This option is required.
=item * method
The subroutine reference which implements the augmentation. This
option is required.
