Here's a simple example using Template::Plugin::Page (which is just
a wrapper around Data::Page). We'll use the Datafile plugin to store
our data.

numbers.dat
-----------

id : name : description
1  : one  : number one
2  : two  : the second number
3  : three : a third number
4  : four : number, the fourth
5  : five : numero cinco
6  : six  : six (not sex)
7  : seven : lucky for some
8  : eight : ate
9  : nine : number nine, number nine

page.tt
-------

[% USE numbers = datafile('numbers.dat') -%]
[% USE page = Page(numbers.size, 4, currpage) -%]
Page [% page.current_page %] of [% page.last_page %]
Entries [% page.first %] to [% page.last %] of [% page.total_entries %]

[% FOREACH num = page.splice(numbers) -%]
  [% num.id %] [% num.name | format('%-8s') %] [% num.description %]
[% END -%]

The template takes one input variable (currpage). For this simple
example we can pass that in using tpage. So, for example:

$ tpage --define currpage=2 page.tt
Page 2 of 3
Entries 5 to 8 of 9

  5 five     numero cinco
  6 six      six (not sex)
  7 seven    lucky for some
  8 eight    ate

$

Does that help?
