Jpegoptim v1.2.3  Copyright (c)  Timo Kokkonen, 1996,2002,2009.

REQUIREMENTS

	Independent JPEG Group's jpeg library version 6a or later

	(jpegsrc.v6a.tar.gz)

TESTED PLATFORMS

	Linux

	Solaris

	Darwin/OSX (compiles fine as 64bit app on Snow Leopard)

INSTALLATION

	Installation should be very straightforward, just unpack the

	tar file, make nesessary changes to the Makefile,  and then

        compile the program. You may wanna do something like this:

		zcat jpegoptim-1.2.3.tar.gz | tar xf -

		cd jpegoptim-1.2.3

		./configure

		make

		make strip

		make install

USAGE

  Basic Usage;

    $ jpegoptim -p -o -dest=./compressed --strip-all -m90

  To do a recursive find of all jpg files & optimize to 60%, preserving original timestamps, overwriting original files;

    $ find . -iname *.jpg -exec jpegoptim -p -m60 --strip-all {} \;

HISTORY

  v1.2.4 - Improved error messaging for rename() calls by Glenn Roberts (Jun 2010)

    minor code clean up.

	v1.2.3 - IPTC marker support by Dustin Ward,

		 ICC profile support by Dwight Kelly,

		 minor fixes

	v1.2.2 - Now Exif and COM markers are not discarded

                 (all other markers are discarded as before).

	         New options --strip-all, --strip-exif, and --strip-com

	         added for controlling what markers to strip.

	v1.2.1 - fixed buggy temp file handling

	v1.2.0 - Added new options --overwrite and --preserve.

		 GNU autoconf support added, also.

	v1.1   - new -f option, and other minor changes, improved

	 	 support for other platforms

	v1.0a  - some changes in docs & makefile

	v1.0   - first public release

TROUBLESHOOTING

  On OSX 10.5.x you might get an "Operation not permitted" error if your JPEGs are on a mounted volume. i.e.;

    renaming: jpegoptim-0-4778.tmp to blah123.JPG

    Rename error: Operation not permitted

    jpegoptim: cannot rename temp file.

  This might fixed with;

    $ chflags -R nouchg .
