3099 * character. The other possible values are either 'array' or 'list'. The
3100 * 'array' value will return an array of the paginated link list to offer full
3101 * control of display. The 'list' value will place all of the paginated links in
3102 * an unordered HTML list.
3103 *
3104 * The 'total' argument is the total amount of pages and is an integer. The
3105 * 'current' argument is the current page number and is also an integer.
3106 *
3107 * An example of the 'base' argument is "http://example.com/all_posts.php%_%"
3108 * and the '%_%' is required. The '%_%' will be replaced by the contents of in
3109 * the 'format' argument. An example for the 'format' argument is "?page=%#%"
3110 * and the '%#%' is also required. The '%#%' will be replaced with the page
3111 * number.
3112 *
3113 * You can include the previous and next links in the list by setting the
3114 * 'prev_next' argument to true, which it is by default. You can set the
3115 * previous text, by using the 'prev_text' argument. You can set the next text
3116 * by setting the 'next_text' argument.
3117 *
3118 * If the 'show_all' argument is set to true, then it will show all of the pages
3119 * instead of a short list of the pages near the current page. By default, the
3120 * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
3121 * arguments. The 'end_size' argument is how many numbers on either the start
3122 * and the end list edges, by default is 1. The 'mid_size' argument is how many
3123 * numbers to either side of current page, but not including current page.
3124 *
3125 * It is possible to add query vars to the link by using the 'add_args' argument
3126 * and see add_query_arg() for more information.
3127 *
3128 * The 'before_page_number' and 'after_page_number' arguments allow users to
3129 * augment the links themselves. Typically this might be to add context to the
3130 * numbered links so that screen reader users understand what the links are for.
3131 * The text strings are added before and after the page number - within the
3132 * anchor tag.
