689 * parameter is used to describe the link.
690 *
691 * The 'option' format uses the option HTML element for use in select element.
692 * The value is the url parameter and the before and after parameters are used
693 * between the text description.
694 *
695 * The 'html' format, which is the default, uses the li HTML element for use in

1757 * area. The 'base' argument is used to reference the url, which will be used to
1758 * create the paginated links. The 'format' argument is then used for replacing
1759 * the page number. It is however, most likely and by default, to be used on the
1760 * archive post pages.
1761 *
1762 * The 'type' argument controls format of the returned value. The default is
1763 * 'plain', which is just a string with the links separated by a newline
1764 * character. The other possible values are either 'array' or 'list'. The
1765 * 'array' value will return an array of the paginated link list to offer full
1766 * control of display. The 'list' value will place all of the paginated links in
1767 * an unordered HTML list.
1768 *
1769 * The 'total' argument is the total amount of pages and is an integer. The
1770 * 'current' argument is the current page number and is also an integer.
1771 *
1772 * An example of the 'base' argument is "http://example.com/all_posts.php%_%"
1773 * and the '%_%' is required. The '%_%' will be replaced by the contents of in
1774 * the 'format' argument. An example for the 'format' argument is "?page=%#%"
1775 * and the '%#%' is also required. The '%#%' will be replaced with the page
1776 * number.
1777 *
1778 * You can include the previous and next links in the list by setting the
1779 * 'prev_next' argument to true, which it is by default. You can set the
1780 * previous text, by using the 'prev_text' argument. You can set the next text
1781 * by setting the 'next_text' argument.
1782 *
1783 * If the 'show_all' argument is set to true, then it will show all of the pages
1784 * instead of a short list of the pages near the current page. By default, the
1785 * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
1786 * arguments. The 'end_size' argument is how many numbers on either the start
1787 * and the end list edges, by default is 1. The 'mid_size' argument is how many
1788 * numbers to either side of current page, but not including current page.
1789 *
1790 * It is possible to add query vars to the link by using the 'add_args' argument
1791 * and see {@link add_query_arg()} for more information.
