+
+Role::Tiny - Roles. Like a nouvelle cuisine portion size slice of Moose.
+
+=head1 SYNOPSIS
+
+ package Some::Role;
+
+ use Role::Tiny;
+
+ sub foo { ... }
+
+ sub bar { ... }
+
+ around baz => sub { ... }
+
+ 1;
+
+else where
+
+ package Some::Class;
+
+ use Role::Tiny::With;
+
+ # bar gets imported, but not foo
+ with 'Some::Role';
+
+ sub foo { ... }
+
+ # baz is wrapped in the around modifier by Class::Method::Modifiers
+ sub baz { ... }
+
+ 1;
+
+If you wanted attributes as well, look at L<Moo::Role>.
+
+=head1 DESCRIPTION
+
+C<Role::Tiny> is a minimalist role composition tool.
+
+=head1 ROLE COMPOSITION
+
+Role composition can be thought of as much more clever and meaningful multiple
+inheritance. The basics of this implementation of roles is:
+
+=over 2
+
+=item *
+
+If a method is already defined on a class, that method will not be composed in
+from the role.
+
+=item *
+
+If a method that the role L</requires> to be implemented is not implemented,
+role application will fail loudly.
+
+=back
+
+Unlike L<Class::C3>, where the B<last> class inherited from "wins," role
+composition is the other way around, where the class wins. If multiple roles
+are applied in a single call (single with statement), then if any of their
+provided methods clash, an exception is raised unless the class provides
+a method since this conflict indicates a potential problem.
+
+=head1 IMPORTED SUBROUTINES
+
+=head2 requires
+
+ requires qw(foo bar);
+
+Declares a list of methods that must be defined to compose role.
+
+=head2 with
+
+ with 'Some::Role1';
+
+ with 'Some::Role1', 'Some::Role2';
+
+Composes another role into the current role (or class via L<Role::Tiny::With>).
+
+If you have conflicts and want to resolve them in favour of Some::Role1 you
+can instead write:
+
+ with 'Some::Role1';
+ with 'Some::Role2';
+
+If you have conflicts and want to resolve different conflicts in favour of
+different roles, please refactor your codebase.
+
+=head2 before
+
+ before foo => sub { ... };
+
+See L<< Class::Method::Modifiers/before method(s) => sub { ... } >> for full
+documentation.
+
+Note that since you are not required to use method modifiers,
+L<Class::Method::Modifiers> is lazily loaded and we do not declare it as
+a dependency. If your L<Role::Tiny> role uses modifiers you must depend on
+both L<Class::Method::Modifiers> and L<Role::Tiny>.
+
+=head2 around
+
+ around foo => sub { ... };
+
+See L<< Class::Method::Modifiers/around method(s) => sub { ... } >> for full
+documentation.
+
+Note that since you are not required to use method modifiers,
+L<Class::Method::Modifiers> is lazily loaded and we do not declare it as
+a dependency. If your L<Role::Tiny> role uses modifiers you must depend on
+both L<Class::Method::Modifiers> and L<Role::Tiny>.
+
+=head2 after
+
+ after foo => sub { ... };
+
+See L<< Class::Method::Modifiers/after method(s) => sub { ... } >> for full
+documentation.
+
+Note that since you are not required to use method modifiers,
+L<Class::Method::Modifiers> is lazily loaded and we do not declare it as
+a dependency. If your L<Role::Tiny> role uses modifiers you must depend on
+both L<Class::Method::Modifiers> and L<Role::Tiny>.
+
+=head2 Strict and Warnings
+
+In addition to importing subroutines, using C<Role::Tiny> applies L<strict> and
+L<fatal warnings|perllexwarn/Fatal Warnings> to the caller. It's possible to
+disable these if desired:
+
+ use Role::Tiny;
+ use warnings NONFATAL => 'all';
+
+=head1 SUBROUTINES
+
+=head2 does_role
+
+ if (Role::Tiny::does_role($foo, 'Some::Role')) {
+ ...
+ }
+
+Returns true if class has been composed with role.
+
+This subroutine is also installed as ->does on any class a Role::Tiny is
+composed into unless that class already has an ->does method, so
+
+ if ($foo->does('Some::Role')) {
+ ...
+ }
+
+will work for classes but to test a role, one must use ::does_role directly.
+
+Additionally, Role::Tiny will override the standard Perl C<DOES> method
+for your class. However, if C<any> class in your class' inheritance
+hierarchy provides C<DOES>, then Role::Tiny will not override it.
+
+=head1 METHODS
+
+=head2 apply_roles_to_package
+
+ Role::Tiny->apply_roles_to_package(
+ 'Some::Package', 'Some::Role', 'Some::Other::Role'
+ );
+
+Composes role with package. See also L<Role::Tiny::With>.
+
+=head2 apply_roles_to_object
+
+ Role::Tiny->apply_roles_to_object($foo, qw(Some::Role1 Some::Role2));
+
+Composes roles in order into object directly. Object is reblessed into the
+resulting class.
+
+=head2 create_class_with_roles
+
+ Role::Tiny->create_class_with_roles('Some::Base', qw(Some::Role1 Some::Role2));
+
+Creates a new class based on base, with the roles composed into it in order.
+New class is returned.
+
+=head2 is_role
+
+ Role::Tiny->is_role('Some::Role1')
+
+Returns true if the given package is a role.
+
+=head1 CAVEATS
+
+=over 4
+
+=item * On perl 5.8.8 and earlier, applying a role to an object won't apply any
+overloads from the role to all copies of the object.
+
+=head1 SEE ALSO
+
+L<Role::Tiny> is the attribute-less subset of L<Moo::Role>; L<Moo::Role> is
+a meta-protocol-less subset of the king of role systems, L<Moose::Role>.
+
+If you don't want method modifiers and do want to be forcibly restricted
+to a single role application per class, Ovid's L<Role::Basic> exists. But
+Stevan Little (the L<Moose> author) and I don't find the additional
+restrictions to be amazingly helpful in most cases; L<Role::Basic>'s choices
+are more a guide to what you should prefer doing, to our mind, rather than
+something that needs to be enforced.
