-=head1 NAME
+=head1 DESCRIPTION
-Moose::Object -
+This class is the default base class for all Moose-using classes. When
+you C<use Moose> in this class, your class will inherit from this
+class.
-=head1 SYNOPSIS
+It provides a default constructor and destructor, which run all of the
+C<BUILD> and C<DEMOLISH> methods in the inheritance hierarchy,
+respectively.
-=head1 DESCRIPTION
+You don't actually I<need> to inherit from this in order to use Moose,
+but it makes it easier to take advantage of all of Moose's features.
=head1 METHODS
=over 4
-=item B<meta>
+=item B<< Moose::Object->new(%params|$params) >>
-=item B<new>
+This method calls C<< $class->BUILDARGS(@_) >>, and then creates a new
+instance of the appropriate class. Once the instance is created, it
+calls C<< $instance->BUILD($params) >> for each C<BUILD> method in the
+inheritance hierarchy.
-=item B<BUILDALL>
+=item B<< Moose::Object->BUILDARGS(%params|$params) >>
-=item B<DEMOLISHALL>
+The default implementation of this method accepts a hash or hash
+reference of named parameters. If it receives a single argument that
+I<isn't> a hash reference it throws an error.
-=back
+You can override this method in your class to handle other types of
+options passed to the constructor.
-=head1 BUGS
+This method should always return a hash reference of named options.
-All complex software has bugs lurking in it, and this module is no
-exception. If you find a bug please either email me, or add the bug
-to cpan-RT.
+=item B<< $object->does($role_name) >>
-=head1 CODE COVERAGE
+This returns true if the object does the given role.
-I use L<Devel::Cover> to test the code coverage of my tests, below is the
-L<Devel::Cover> report on this module's test suite.
+=item B<< $object->DOES($class_or_role_name) >>
-=head1 ACKNOWLEDGEMENTS
+This is a a Moose role-aware implementation of L<UNIVERSAL/DOES>.
-=head1 AUTHOR
+This is effectively the same as writing:
-Stevan Little E<lt>stevan@iinteractive.comE<gt>
+ $object->does($name) || $object->isa($name)
-=head1 COPYRIGHT AND LICENSE
+This method will work with Perl 5.8, which did not implement
+C<UNIVERSAL::DOES>.

+=item B<< $object->dump($maxdepth) >>
-L<http://www.iinteractive.com>
+This is a handy utility for C<Data::Dumper>ing an object. By default,
+the maximum depth is 1, to avoid making a mess.
+
+=item B<< $object->DESTROY >>
+
+A default destructor is provided, which calls
+C<< $instance->DEMOLISH($in_global_destruction) >> for each C<DEMOLISH>
+method in the inheritance hierarchy.
