+% dvips syntax: \special{ps: [{ThisPage}<</Rotate 90>> /PUT pdfmark}%
+% There seem to be an in-built management code: multiple uses don't lead to
+% multiple entries (/Rotate is special: there is always a /Rotate 0 in the dict, but seems
+% not to do harm).
+% dvipdfmx syntax: \special{pdf: put @thispage << /Rotate 90 >>}, like dvips has an in-built
+% management code.
+% Both change only the current page, so to get the pdftex behaviour (which sets
+% also the following pages) one need to repeat it on every shipout.
 % Open is the question if one need more shipout hooks to set e.g. Rotate on specific
 % pages. Open is the setter for /AF (and perhaps /OutputIntents).
