Canon MakerNote patch for jhead

Canon MakerNote patch for jhead

1. What is this?

Most of the Canon digital cameras include some of the settings in exif tag known as the MakerNote. This little patch for jhead 2.0 tries to find some useful information from MakerNote tag and print them along with other tags.

I have tested it with my Ixus 300 and Pro90 IS, both work just fine. I have no idea how to apply this thing in Windows or how the patched program behaves with other cameras.
