If you use a capability type like "gpost", which defaults to "post" then
WordPress will automatically generate the edit_gposts, publish_gposts,
delete_gposts (etc) capabilities for you. Additionally, it will know how to
properly handle the edit_gpost, publish_gpost, and delete_gpost meta

If you want finer grained control, you can individual name each of the
capabilities WP would otherwise generate for you based on the capability

See register_post_type() and get_post_type_capabilities(), in
