-/**
- * Retrieve all children of the post parent ID.
- *
- * Normally, without any enhancements, the children would apply to pages. In the
- * context of the inner workings of WordPress, pages, posts, and attachments
- * share the same table, so therefore the functionality could apply to any one
- * of them. It is then noted that while this function does not work on posts, it
- * does not mean that it won't work on posts. It is recommended that you know
- * what context you wish to retrieve the children of.
- *
- * Attachments may also be made the child of a post, so if that is an accurate
- * statement (which needs to be verified), it would then be possible to get
- * all of the attachments for a post. Attachments have since changed since
- * version 2.5, so this is most likely unaccurate, but serves generally as an
- * example of what is possible.
- *
- * The arguments listed as defaults are for this function and also of the
- * {@link get_posts()} function. The arguments are combined with the
- * get_children defaults and are then passed to the {@link get_posts()}
- * function, which accepts additional arguments. You can replace the defaults in
- * this function, listed below and the additional arguments listed in the
- * {@link get_posts()} function.
- *
- * The 'post_parent' is the most important argument and important attention
- * needs to be paid to the $args parameter. If you pass either an object or an
- * integer (number), then just the 'post_parent' is grabbed and everything else
- * is lost. If you don't specify any arguments, then it is assumed that you are
- * in The Loop and the post parent will be grabbed for from the current post.
- *
- * The 'post_parent' argument is the ID to get the children. The 'numberposts'
- * is the amount of posts to retrieve that has a default of '-1', which is
- * used to get all of the posts. Giving a number higher than 0 will only
- * retrieve that amount of posts.
- *
- * The 'post_type' and 'post_status' arguments can be used to choose what
- * criteria of posts to retrieve. The 'post_type' can be anything, but WordPress
- * post types are 'post', 'pages', and 'attachments'. The 'post_status'
- * argument will accept any post status within the write administration panels.
- *
- * @see get_posts() Has additional arguments that can be replaced.
- * @internal Claims made in the long description might be inaccurate.
- *
- * @since 2.0.0
- *
- * @param mixed $args Optional. User defined arguments for replacing the defaults.
- * @param string $output Optional. Constant for return type, either OBJECT (default), ARRAY_A, ARRAY_N.
- * @return array|bool False on failure and the type will be determined by $output parameter.

-/**
- * 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).
- *
- * @see map_meta_cap()
- * @since 3.0.0
- *
- * @param object $args Post type registration arguments
