1609   *
1610   * Technically, the function can be used to create paginated link list for any
1611   * area. The 'base' argument is used to reference the url, which will be used to
1612   * create the paginated links. The 'format' argument is then used for replacing
1613   * the page number. It is however, most likely and by default, to be used on the
1614   * archive post pages.
1615   *
1616   * The 'type' argument controls format of the returned value. The default is
1617   * 'plain', which is just a string with the links separated by a newline
1618   * character. The other possible values are either 'array' or 'list'. The
1619   * 'array' value will return an array of the paginated link list to offer full
1620   * control of display. The 'list' value will place all of the paginated links in
1621   * an unordered HTML list.
1622   *
1623   * The 'total' argument is the total amount of pages and is an integer. The
1624   * 'current' argument is the current page number and is also an integer.
1625   *
1626   * An example of the 'base' argument is "http://example.com/all_posts.php%_%"
1627   * and the '%_%' is required. The '%_%' will be replaced by the contents of in
1628   * the 'format' argument. An example for the 'format' argument is "?page=%#%"
1629   * and the '%#%' is also required. The '%#%' will be replaced with the page
1630   * number.
1631   *
1632   * You can include the previous and next links in the list by setting the
1633   * 'prev_next' argument to true, which it is by default. You can set the
1634   * previous text, by using the 'prev_text' argument. You can set the next text
1635   * by setting the 'next_text' argument.
1636   *
1637   * If the 'show_all' argument is set to true, then it will show all of the pages
1638   * instead of a short list of the pages near the current page. By default, the
1639   * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
1640   * arguments. The 'end_size' argument is how many numbers on either the start
1641   * and the end list edges, by default is 1. The 'mid_size' argument is how many
1642   * numbers to either side of current page, but not including current page.
1643   *
1644   * It is possible to add query vars to the link by using the 'add_args' argument
1645   * and see {@link add_query_arg()} for more information.
