<info>
The Pager Tag Library helps generate Google[sm] and AltaVista�
style search result navigators. It will take multiple pages worth of
information, dynamically split it up into page sized pieces and generate
a browsable index. It does this in a flexible way that allows designers
to give the index just about any look desired.
