portland – Simple portrait/landscape switching
The portland package provides portrait and landscape environments, that set page dimensions but don't provide any hints to output devices. Thus, while you can sometimes read the resulting text in a previewer, special measures have to be taken to print the output.

- landscape: Set up for typesetting in landscape
- pos-at: Position things at absolute positions on the page
