   4  *   Public file definitions for the Common UNIX Printing System (CUPS).

   6  *   Since stdio files max out at 256 files on many systems, we have to
   7  *   write similar functions without this limit.  At the same time, using
   8  *   our own file functions allows us to provide transparent support of
   9  *   gzip'd print files, PPD files, etc.
