1630:
1631: See lonhelper.pm documentation for discussion of the helper framework.
1632:
1633: Apache::lonprintout::page_size_state is an element that gives the
1634: user the opportunity to further refine the page settings if they
1635: select a single-column page.
1636:
1637: page_size_state is always directly invoked in lonprintout.pm, so there
1638: is no tag interface. You actually pass parameters to the constructor.
