| * create the paginated links. The 'format' argument is then used for replacing |
| * the page number. It is however, most likely and by default, to be used on the |
| * archive post pages. |
| * |
| * The 'type' argument controls format of the returned value. The default is |
| * 'plain', which is just a string with the links separated by a newline |
| * character. The other possible values are either 'array' or 'list'. The |
| * 'array' value will return an array of the paginated link list to offer full |
| * control of display. The 'list' value will place all of the paginated links in |
| * an unordered HTML list. |
| * |
| * The 'total' argument is the total amount of pages and is an integer. The |
| * 'current' argument is the current page number and is also an integer. |
| * |
| * An example of the 'base' argument is "http://example.com/all_posts.php%_%" |
| * and the '%_%' is required. The '%_%' will be replaced by the contents of in |
| * the 'format' argument. An example for the 'format' argument is "?page=%#%" |
| * and the '%#%' is also required. The '%#%' will be replaced with the page |
| * number. |
| * |
| * You can include the previous and next links in the list by setting the |
| * 'prev_next' argument to true, which it is by default. You can set the |
| * previous text, by using the 'prev_text' argument. You can set the next text |
| * by setting the 'next_text' argument. |
| * |
| * If the 'show_all' argument is set to true, then it will show all of the pages |
| * instead of a short list of the pages near the current page. By default, the |
| * 'show_all' is set to false and controlled by the 'end_size' and 'mid_size' |
| * arguments. The 'end_size' argument is how many numbers on either the start |
| * and the end list edges, by default is 1. The 'mid_size' argument is how many |
| * numbers to either side of current page, but not including current page. |
| * |

| * and see {@link add_query_arg()} for more information. |
