Script to rotate images with no loss of information (as it appears in the
Debian libjpeg-progs package)

The script exifautotran (attached) does exactly the right thing;

1) Rotates losslessly, using jpegtran
2) Preserves all metadata, using the switch "-copy all" to jpegtran
3) Resets orientation, using jpegexiforient -1
4) Includes error handling
