=head1 NAME
Moo - Minimalist Object Orientation (with Moose compatiblity)
-=head1 WARNING WARNING WARNING
-
-This is a 0.9 release because we're fairly sure it works. For us. Until it's
-tested in the wild, we make no guarantees it also works for you.
-
-If this module does something unexpected, please submit a failing test.
-
-But if it eats your cat, sleeps with your boyfriend, or pushes grandma down
-the stairs to save her from the terrible secret of space, it's not our fault.

=head1 SYNOPSIS
package Cat::Food;
=head2 BUILDARGS
-This feature from Moose is not yet supported.
+ around BUILDARGS => sub {
+ my $orig = shift;
+ my ( $class, @args ) = @_;
+
+ unshift @args, "attr1" if @args % 2 == 1;
+
+ return $class->$orig(@args);
+ };
+
+ Foo::Bar->new( 3 );
+
+The default implementation of this method accepts a hash or hash reference of
+named parameters. If it receives a single argument that isn't a hash reference
+it throws an error.
+
+You can override this method in your class to handle other types of options
+passed to the constructor.
-=head2 BUILDALL
+This method should always return a hash reference of named options.
-Don't override (or probably even call) this method. Instead, you can define
-a C<BUILD> method on your class and the constructor will automatically call the
-C<BUILD> method from parent down to child after the object has been
-instantiated. Typically this is used for object validation or possibly logging.
+=head2 BUILD
+
+Define a C<BUILD> method on your class and the constructor will automatically
+call the C<BUILD> method from parent down to child after the object has
+been instantiated. Typically this is used for object validation or possibly
+logging.
+
+=head2 DEMOLISH
+
+If you have a C<DEMOLISH> method anywhere in your inheritance hierarchy,
+a C<DESTROY> method is created on first object construction which will call
+C<< $instance->DEMOLISH($in_global_destruction) >> for each C<DEMOLISH>
+method from child upwards to parents.
+
+Note that the C<DESTROY> method is created on first construction of an object
+of your class in order to not add overhead to classes without C<DEMOLISH>
+methods; this may prove slightly surprising if you try and define your own.

=item * coerce
-This Moose feature is not yet supported
-
-=begin hide
-
Takes a coderef which is meant to coerce the attribute. The basic idea is to
do something like the following:
$_[0] + 1 unless $_[0] % 2
},
+Coerce does not require C<isa> to be defined.
+
L<Sub::Quote aware|/SUB QUOTE AWARE>
-=end hide
+=item * handles
+
+Takes a string
+
+ handles => 'RobotRole'
+
+Where C<RobotRole> is a role (L<Moo::Role>) that defines an interface which
+becomes the list of methods to handle.
+
+Takes a list of methods
+
+ handles => [ qw( one two ) ]
+
+Takes a hashref
+
+ handles => {
+ un => 'one',
+ }
=item * trigger
B<Boolean>. Set this if the attribute must be passed on instantiation.
+=item * reader
+
+The value of this attribute will be the name of the method to get the value of
+the attribute. If you like Java style methods, you might set this to
+C<get_foo>
+
+=item * writer
+
+The value of this attribute will be the name of the method to set the value of
+the attribute. If you like Java style methods, you might set this to
+C<set_foo>
+
=item * weak_ref
B<Boolean>. Set this if you want the reference that the attribute contains to
C<documentation> is not supported since it's a very poor replacement for POD.
+Handling of warnings: when you C<use Moo> we enable FATAL warnings. The nearest
+similar invocation for L<Moose> would be:
+
+ use Moose;
+ use warnings FATAL => "all";
+
+Additionally, L<Moo> supports a set of attribute option shortcuts intended to
+reduce common boilerplate. The set of shortcuts is the same as in the L<Moose>
+module L<MooseX::AttributeShortcuts>. So if you:
+
+ package MyClass;
+ use Moo;
+
+The nearest L<Moose> invocation would be:
+
+ package MyClass;
+
+ use Moose;
+ use warnings FATAL => "all";
+ use MooseX::AttributeShortcuts;
