Converting RAW images to JPEG with Exif on Fedora

I have a Canon 350D camera, used to use raw format to save photos and use Canon DPP software to convert photos to jpeg format. Picasa2 is my favorite photo organizer because it can directly show raw photos but it can’t export jpeg format with Exif, such camera model, len information, etc. So I used Canon DPP to do the job on Windows. On Fedora, we don’t have Canon DPP. Although OS X has DPP, but no Picasa2. I wrote a simple script, it uses dcraw, cjpeg and exiv2 to do the conversion job. Here is the script (Download Here):
