/** \file
|
|
* Conception:
|
|
* Generalized output-in-pages. Allows the current content to be 'printed':
|
|
* either into a pdf file (any other later?) or to any kind of other output
|
|
* destination that divides the website into pages - as a printer.
|
|
* The basic usage is calling print_basic_run which sets everything up,
|
|
* prints page after page until the whole content is printed and cleans
|
|
* everyting up.
|
|
* If there are any other, printer specific routines to be performed in the
|
|
* meantime - there can be set up any other printing funcion, which can use
|
|
* print_set_up, print_draw_next_page and print_cleanup directly.
