Jhead: Exif Jpeg header manipulation tool

Let's say one needs to modify/manipulate the header of .jpg files. Obviously, one would need some sort of a tool to do that. So, I searched for something/anything to help me, and I found this little command line tool called Jhead (documentation can be found here) which helped me get the job done.

Thank you. It's simple and did exactly what I needed it to do.
