%
% All text, within the \texttt{landscape} environment is rotated through
% 90 degrees. The environment may span several pages. It works well
% with, and was originally created for, use with \textsf{longtable} to
% produce long wide tables.
%
% All the work is done by the \textsf{graphics} package, the trick is to
% call it at the right place in the output routine to rotate the current
% page before the page head and foot are added.

% Here is what Scott Pakin wrote about the pdftex option:
% \begin{quote}
% I've made a minor improvement to lscape.dtx that I'd like to share
% with the world. My addition makes lscape rotate the PDF "paper" --
% not just the text on the page -- when given the "pdftex" option.
% (Naturally, this works only with pdfLaTeX.) The result is that the
% text is viewable online without the reader having to rotate his/her
% head 90 degrees. The document still prints normally.
