+ * 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.

+/**
+ * Register a post type. Do not use before init.
+ *
+ * A function for creating or modifying a post type based on the
+ * parameters given. The function will accept an array (second optional
+ * parameter), along with a string for the post type name.
+ *
+ * Optional $args contents:
+ *
+ * - label - Name of the post type shown in the menu. Usually plural. If not set, labels['name'] will be used.
+ * - description - A short descriptive summary of what the post type is. Defaults to blank.
+ * - public - Whether posts of this type should be shown in the admin UI. Defaults to false.
+ * - exclude_from_search - Whether to exclude posts with this post type from search results.
+ *     Defaults to true if the type is not public, false if the type is public.
+ * - publicly_queryable - Whether post_type queries can be performed from the front page.
+ *     Defaults to whatever public is set as.
+ * - show_ui - Whether to generate a default UI for managing this post type. Defaults to true
+ *     if the type is public, false if the type is not public.
+ * - show_in_menu - Where to show the post type in the admin menu. True for a top level menu,
+ *     false for no menu, or can be a top level page like 'tools.php' or 'edit.php?post_type=page'.
+ *     show_ui must be true.
+ * - menu_position - The position in the menu order the post type should appear. Defaults to the bottom.
+ * - menu_icon - The url to the icon to be used for this menu. Defaults to use the posts icon.
+ * - capability_type - The string to use to build the read, edit, and delete capabilities. Defaults to 'post'.
+ *   May be passed as an array to allow for alternative plurals when using this argument as a base to construct the
+ *   capabilities, e.g. array('story', 'stories').
+ * - capabilities - Array of capabilities for this post type. By default the capability_type is used
+ *      as a base to construct capabilities. 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.
+ * - hierarchical - Whether the post type is hierarchical. Defaults to false.
+ * - supports - An alias for calling add_post_type_support() directly. See {@link add_post_type_support()}
+ *     for documentation. Defaults to none.
+ * - register_meta_box_cb - Provide a callback function that will be called when setting up the
+ *     meta boxes for the edit form.  Do remove_meta_box() and add_meta_box() calls in the callback.
+ * - taxonomies - An array of taxonomy identifiers that will be registered for the post type.
+ *     Default is no taxonomies. Taxonomies can be registered later with register_taxonomy() or
+ *     register_taxonomy_for_object_type().
+ * - labels - An array of labels for this post type. By default post labels are used for non-hierarchical
+ *     types and page labels for hierarchical ones. You can see accepted values in {@link get_post_type_labels()}.
+ * - permalink_epmask - The default rewrite endpoint bitmasks.
+ * - has_archive - True to enable post type archives. Will generate the proper rewrite rules if rewrite is enabled.
+ * - rewrite - false to prevent rewrite. Defaults to true. Use array('slug'=>$slug) to customize permastruct;
+ *     default will use $post_type as slug. Other options include 'with_front', 'feeds', and 'pages'.
+ * - query_var - false to prevent queries, or string to value of the query var to use for this post type
+ * - can_export - true allows this post type to be exported.
+ * - show_in_nav_menus - true makes this post type available for selection in navigation menus.
+ * - _builtin - true if this post type is a native or "built-in" post_type. THIS IS FOR INTERNAL USE ONLY!
+ * - _edit_link - URL segement to use for edit link of this post type. THIS IS FOR INTERNAL USE ONLY!
+ *

+ * 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).

+ * order - Default is ASC. Can use DESC.
+ *
+ * hide_empty - Default is true. Will not return empty terms, which means
+ * terms whose count is 0 according to the given taxonomy.
+ *
+ * exclude - Default is an empty array.  An array, comma- or space-delimited string
+ * of term ids to exclude from the return array.  If 'include' is non-empty,
+ * 'exclude' is ignored.
+ *
+ * exclude_tree - Default is an empty array.  An array, comma- or space-delimited

+ * descendant terms according to the primary taxonomy.  If 'include' is non-empty,
+ * 'exclude_tree' is ignored.
+ *
+ * include - Default is an empty array.  An array, comma- or space-delimited string
+ * of term ids to include in the return array.
+ *
+ * number - The maximum number of terms to return.  Default is to return them all.
+ *
+ * offset - The number by which to offset the terms query.
+ *
+ * fields - Default is 'all', which returns an array of term objects.
+ * If 'fields' is 'ids' or 'names', returns an array of
+ * integers or strings, respectively.
+ *
+ * slug - Returns terms whose "slug" matches this value. Default is empty string.
+ *
+ * hierarchical - Whether to include terms that have non-empty descendants
+ * (even if 'hide_empty' is set to true).
+ *
+ * search - Returned terms' names will contain the value of 'search',
+ * case-insensitive.  Default is an empty string.

+ * name__like - Returned terms' names will begin with the value of 'name__like',
+ * case-insensitive. Default is empty string.
+ *
+ * The argument 'pad_counts', if set to true will include the quantity of a term's

+ *
+ * The 'get' argument, if set to 'all' instead of its default empty string,

+ *
+ * The 'child_of' argument, when used, should be set to the integer of a term ID.  Its default

+ * of that term according to the given taxonomy.  Hence 'child_of' is set to 0
+ * if more than one taxonomy is passed in $taxonomies, because multiple taxonomies
+ * make term ancestry ambiguous.
+ *
+ * The 'parent' argument, when used, should be set to the integer of a term ID.  Its default is
+ * the empty string '', which has a different meaning from the integer 0.

+ *
+ * 'slug'. Expected to be a string. There is no default.
+ *
+ * If 'slug' argument exists then the slug will be checked to see if it is not
+ * a valid term. If that check succeeds (it is not a valid term), then it is
+ * added and the term id is given. If it fails, then a check is made to whether
