I generate PDF files by several methods such as LaTeX and PostScript
programs and view them with the excellent Adobe Reader or Adobe
Acrobat Professional. When I create a new PDF I want the Adobe Reader
to realize that the file has changed and to update the display while
keeping on the same page. How do I do this?
Note: The functionality to watch a file is in my atchange program
(http://alum.mit.edu/www/toms/atchange.html). Atchange watches a file
and then does something for me. I can have it pop up a new Adobe
Reader once the new PDF has been generated, but after a while my
screen is covered with old versions and deleting them is quite a
chore. Having Adobe Reader update automatically every second (for
example) would be a great time saver.
