 761          * a structured array of links usually used for the tabs in a skin
 762          *
 763          * There are 4 standard sections
 764          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 765          * views: Used for primary page views like read, edit, history
 766          * actions: Used for most extra page actions like deletion, protection, etc...
 767          * variants: Used to list the language variants for the page
 768          *
 769          * Each section's value is a key/value array of links for that section.
 770          * The links themseves have these common keys:
 771          * - class: The css classes to apply to the tab
 772          * - text: The text to display on the tab
 773          * - href: The href for the tab to point to
 774          * - rel: An optional rel= for the tab's link
 775          * - redundant: If true the tab will be dropped in skins using content_actions
 776          *   this is useful for tabs like "Read" which only have meaning in skins that
 777          *   take special meaning from the grouped structure of content_navigation
 778          *
 779          * Views also have an extra key which can be used:
 780          * - primary: If this is not true skins like vector may try to hide the tab
 781          *            when the user has limited space in their browser window
 782          *
 783          * content_navigation using code also expects these ids to be present on the
 784          * links, however these are usually automatically generated by SkinTemplate
 785          * itself and are not necessary when using a hook. The only things these may
 786          * matter to are people modifying content_navigation after it's initial creation:
 787          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 788          * - tooltiponly: This is set to true for some tabs in cases where the system
 789          *                believes that the accesskey should not be added to the tab.
 790          *
 791          * @return array

1619          * Makes a link, usually used by makeListItem to generate a link for an item
1620          * in a list used in navigation lists, portlets, portals, sidebars, etc...
1621          *
1622          * @param $key string usually a key from the list you are generating this
1623          * link from.
1624          * @param $item array contains some of a specific set of keys.
1625          *
1626          * The text of the link will be generated either from the contents of the
1627          * "text" key in the $item array, if a "msg" key is present a message by
1628          * that name will be used, and if neither of those are set the $key will be
1629          * used as a message name.
1630          *
1631          * If a "href" key is not present makeLink will just output htmlescaped text.
1632          * The "href", "id", "class", "rel", and "type" keys are used as attributes
1633          * for the link if present.
1634          *
1635          * If an "id" or "single-id" (if you don't want the actual id to be output
1636          * on the link) is present it will be used to generate a tooltip and
1637          * accesskey for the link.
1638          *
1639          * If you don't want an accesskey, set $item['tooltiponly'] = true;
1640          *
1641          * @param $options array can be used to affect the output of a link.
1642          * Possible options are:
1643          *   - 'text-wrapper' key to specify a list of elements to wrap the text of
1644          *   a link in. This should be an array of arrays containing a 'tag' and
1645          *   optionally an 'attributes' key. If you only have one element you don't
1646          *   need to wrap it in another array. eg: To use <a><span>...</span></a>
1647          *   in all links use array( 'text-wrapper' => array( 'tag' => 'span' ) )
1648          *   for your options.
1649          *   - 'link-class' key can be used to specify additional classes to apply
1650          *   to all links.
1651          *   - 'link-fallback' can be used to specify a tag to use instead of "<a>"
1652          *   if there is no link. eg: If you specify 'link-fallback' => 'span' than
1653          *   any non-link will output a "<span>" instead of just text.
1654          *
