Probably only useful for components. =head1 METHODS =head2 get_namespace_parts Returns the namespace and class name of a package. See L</SYNOPSIS> for example. =head2 is_load_namespaces Returns true if a package is structured in a way that would work for load_namespaces. See L</SYNOPSIS> for example. =head2 is_not_load_namespaces Returns true if a package is structured in a way that would not work for load_namespaces. See L</SYNOPSIS> for example. =head2 assert_similar_namespaces Dies if both packages are structured in the same way. The same means both are load_namespaces or both are not. See L</SYNOPSIS> for example. =head1 AUTHOR Arthur Axel "fREW" Schmidt <frioux+cpan@gmail.com> =head1 COPYRIGHT AND LICENSE This software is copyright (c) 2009 by Arthur Axel "fREW" Schmidt.
