+ * 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.
+ *

+ * 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).
