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 . (As per http://stackoverflow.com/questions/1765232/subclipse-cant-rename-file-os-x)
