/**
* Builds an object with all post type capabilities out of a post type object

- * - edit_post - The meta capability that controls editing a particular object of this post type. Defaults to "edit_ . $capability_type" (edit_post).
- * - edit_posts - The capability that controls editing objects of this post type as a class. Defaults to "edit_ . $capability_type . s" (edit_posts).
- * - edit_others_posts - The capability that controls editing objects of this post type that are owned by other users. Defaults to "edit_others_ . $capability_type . s" (edit_others_posts).
- * - publish_posts - The capability that controls publishing objects of this post type. Defaults to "publish_ . $capability_type . s" (publish_posts).
- * - read_post - The meta capability that controls reading a particular object of this post type. Defaults to "read_ . $capability_type" (read_post).
- * - read_private_posts - The capability that controls reading private posts. Defaults to "read_private . $capability_type . s" (read_private_posts).
- * - delete_post - The meta capability that controls deleting a particular object of this post type. Defaults to "delete_ . $capability_type" (delete_post).
- *
+ * 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

+ * behave like delete_posts.
+ * - edit_private_posts - Controls whether private objects can be edited.
+ * - edit_published_posts - Controls whether published objects can be deleted.
+ *
