     Miscellaneous Options:
       -debug events        display copious debugging information
       -help                print program options

     arguments
       -version             print version information

     By  default, the image format of `file' is determined by its
     magic number.  To specify a particular image format, precede
     the  filename  with  an  image format name and a colon (i.e.
     ps:image) or specify the image type as the  filename  suffix
     (i.e.  image.ps).   Specify 'file' as '-' for standard input
     or output.
