+ * Builds an object with all post type capabilities out of a post type object
+ *
+ * Post type capabilities use the 'capability_type' argument as a base, if the
+ * capability is not set in the 'capabilities' argument array or if the
+ * 'capabilities' argument is not supplied.
+ *
+ * The capability_type argument can optionally be registered as an array, with
+ * the first value being singular and the second plural, e.g. array('story, 'stories')
+ * Otherwise, an 's' will be added to the value for the plural form. After
+ * registration, capability_type will always be a string of the singular value.
+ *
+ * By default, seven keys are accepted as part of the capabilities array:
+ *
+ * - edit_post, read_post, and delete_post are meta capabilities, which are then
+ * generally mapped to corresponding primitive capabilities depending on the
+ * context, which would be the post being edited/read/deleted and the user or
+ * role being checked. Thus these capabilities would generally not be granted
+ * directly to users or roles.
+ *
+ * - edit_posts - Controls whether objects of this post type can be edited.
+ * - edit_others_posts - Controls whether objects of this type owned by other users
+ * can be edited. If the post type does not support an author, then this will
+ * behave like edit_posts.
+ * - publish_posts - Controls publishing objects of this post type.
+ * - read_private_posts - Controls whether private objects can be read.
+
+ * These four primitive capabilities are checked in core in various locations.
+ * There are also seven other primitive capabilities which are not referenced
+ * directly in core, except in map_meta_cap(), which takes the three aforementioned
+ * meta capabilities and translates them into one or more primitive capabilities
+ * that must then be checked against the user or role, depending on the context.
+ *
+ * - read - Controls whether objects of this post type can be read.
+ * - delete_posts - Controls whether objects of this post type can be deleted.
+ * - delete_private_posts - Controls whether private objects can be deleted.
+ * - delete_published_posts - Controls whether published objects can be deleted.
+ * - delete_others_posts - Controls whether objects owned by other users can be
+ * can be deleted. If the post type does not support an author, then this will
+ * behave like delete_posts.
+ * - edit_private_posts - Controls whether private objects can be edited.
+ * - edit_published_posts - Controls whether published objects can be deleted.
+ *
+ * These additional capabilities are only used in map_meta_cap(). Thus, they are
+ * only assigned by default if the post type is registered with the 'map_meta_cap'
+ * argument set to true (default is false).
