NAME
       jpeginfo	- prints information and tests integrity of JPEG/JFIF files.

SYNOPSIS
       jpeginfo	[ options ] [ filenames	]

DESCRIPTION
       jpeginfo	 is  used  to generate informative listings of jpeg files, and
       also to check jpeg files	for errors. Program  also  supports  automatic
       deletion	of broken jpegs.

OPTIONS
       Options	may be either the traditional POSIX one	letter options,	or the
       GNU style long options.	POSIX style options start with a single	``-'',
       while GNU long options start with ``--''.

       Options offered by jpeginfo are the following:

       -c, --check
	     Check  files  also	for errors. (default is	just to	read the head-
	     ers).

       -C, --comments
	     Display file comments (from COM markers).

       -d, --delete
	     Delete files that have errors. (default  is  not  to  delete  any
	     files).

       -f<filename>, --file<filename>
	     Read  filenames to	process	from given file. To use	standard input
	     (stdin) use '-' as	a filename. This  is  alternative  to  default
	     where filenames are given as parameters to	the program.

       -h, --help
	     Display short usage information and exits.

       -5, --md5
	     Calculates	MD5 checksum for each file.

       -i, --info
	     Displays  even  more information about each picture. Prints image
	     coding (Huffman/Arithmetic), density (in  dpi/dpc),  and  whether
	     CCIR601 sampling was used or not.

       -l, --lsstyle
	     Uses alternate listing format (ls -l style).

       -v, --verbose
	     Enables verbose mode (positively chatty).

       --version
	     Displays program version.

       -q, --quiet
	     Quiet mode, output	just the jpeg infos.

       -m<mode>, --mode=<mode>
	     Sets  the	delete	mode,  meaningful only when used with -d flag.
	     Mode can be one of	the following:

	     all    files containing any type of errors/warnings, not  nesses-
		    sary preventing the	decoding. (default)

	     erronly
		    only  files	 with serious errors (ie. cannot be decoded at
		    all).

BUGS
       None, so	far :-)
