+=head1 VERSION
+
+This document describes Mouse version 0.41
=head1 METHODS
-=head2 new arguments -> object
+=head2 C<< new (Arguments) -> Object >>
+
+Instantiates a new C<Mouse::Object>. This is obviously intended for subclasses.
-Instantiates a new Mouse::Object. This is obviously intended for subclasses.
+=head2 C<< BUILDARGS (Arguments) -> HashRef >>
-=head2 BUILDALL \%args
+Lets you override the arguments that C<new> takes. Return a hashref of
+parameters.
-Calls L</BUILD> on each class in the class hierarchy. This is called at the
-end of L</new>.
+=head2 C<< BUILDALL (\%args) >>
-=head2 BUILD \%args
+Calls C<BUILD> on each class in the class hierarchy. This is called at the
+end of C<new>.
+
+=head2 C<< BUILD (\%args) >>
You may put any business logic initialization in BUILD methods. You don't
need to redispatch or return any specific value.
-=head2 DEMOLISHALL
+=head2 C<< DEMOLISHALL >>
-Calls L</DEMOLISH> on each class in the class hierarchy. This is called at
-L</DESTROY> time.
+Calls C<DEMOLISH> on each class in the class hierarchy. This is called at
+C<DESTROY> time.
-=head2 DEMOLISH
+=head2 C<< DEMOLISH >>
You may put any business logic deinitialization in DEMOLISH methods. You don't
need to redispatch or return any specific value.
+
+=head2 C<< does ($role_name) -> Bool >>
+
+This will check if the invocant's class B<does> a given C<$role_name>.
+This is similar to "isa" for object, but it checks the roles instead.
+
+=head2 C<<dump ($maxdepth) -> Str >>
+
+From the Moose POD:
+
+ C'mon, how many times have you written the following code while debugging:
+
+ use Data::Dumper;
+ warn Dumper $obj;
+
+ It can get seriously annoying, so why not just use this.
+
+The implementation was lifted directly from Moose::Object.
