libdata-page-perl binary package in Ubuntu Focal amd64

 When searching through large amounts of data, it is often the case
 that a result set is returned that is larger than is desired to display
 on a single page. This results in wanting to page through multiple pages of
 data. The maths behind this is unfortunately fiddly, hence this
 Data::Page module.
 .
 After specifying the total number of entries, the desired number of entries
 per page, and the current page number, Data::Page will calculate how many pages
 of information there are, and what number the first and last entries on the
 current page really are.
