This +results in wanting to page through various pages of data. The maths behind this +is unfortunately fiddly, hence this module. + +The main concept is that you pass in the number of total entries, the number of +entries per page, and the current page number. You can then call methods to +find out how many pages of information there are, and what number the first and +last entries on the current page really are. |
