+ * - description - A short descriptive summary of what the post type is. Defaults to blank.
+ * - public - Whether a post type is intended for use publicly either via the admin interface or by front-end users.
+ * * Defaults to false.
+ * * While the default settings of exclude_from_search, publicly_queryable, show_ui, and show_in_nav_menus are
+ * inherited from public, each does not rely on this relationship and controls a very specific intention.
+ * - hierarchical - Whether the post type is hierarchical (e.g. page). Defaults to false.

+ * * ?{post_type_key}={single_post_slug}
+ * * ?{post_type_query_var}={single_post_slug}

+ * - show_ui - Whether to generate a default UI for managing this post type in the admin.
+ * * If not set, the default is inherited from public.
+ * - show_in_menu - Where to show the post type in the admin menu.
+ * * If true, the post type is shown in its own top level menu.
+ * * If false, no menu is shown
+ * * If a string of an existing top level menu (eg. 'tools.php' or 'edit.php?post_type=page'), the post type will
+ * be placed as a sub menu of that.
+ * * show_ui must be true.

+ * * Defaults to null, which places it at the bottom of its area.
+ * - menu_icon - The url to the icon to be used for this menu. Defaults to use the posts icon.

+ * * You can see accepted values in {@link get_post_type_capabilities()}.
+ * - map_meta_cap - Whether to use the internal default meta capability handling. Defaults to false.
+ * - supports - An alias for calling add_post_type_support() directly. Defaults to title and editor.
+ * * See {@link add_post_type_support()} for documentation.
+ * - register_meta_box_cb - Provide a callback function that sets up the meta boxes
+ * for the edit form. Do remove_meta_box() and add_meta_box() calls in the callback.

+ * * Default is no taxonomies.
+ * * Taxonomies can be registered later with register_taxonomy() or register_taxonomy_for_object_type().
+ * - has_archive - True to enable post type archives. Default is false.
+ * * Will generate the proper rewrite rules if rewrite is enabled.
+ * - rewrite - Triggers the handling of rewrites for this post type. Defaults to true, using $post_type as slug.
+ * * To prevent rewrite, set to false.
+ * * To specify rewrite rules, an array can be passed with any of these keys
+ * * 'slug' => string Customize the permastruct slug. Defaults to $post_type key

+ * 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 edited.
+ *
+ * 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).
