% This file can be prepended to most PostScript pages to force
% rotation to "landscape" mode.
%
% There are (at least) four possible ways to reasonably position a
% page after rotation.  Any of the four old corners (llx,lly e.g.)
% can be moved to match the corresonding new corner.
% By uncommmenting the appropriate line below (i.e., remove the
% leading '%'), any such positioning can be chosen for positive or
% negative rotation.  The comments at the end of each "rotate" line
% indicate the ORIGINAL corner to be aligned. For example, as given
% below, the lower left hand corner is aligned.  When viewed, this
% corner will have moved to the urx,lly corner.
