[libextractor] duplicate "software" fields for image/x-canon-cr2

[David Lasker]

I am a libextractor newbie attempting to use it with Mediatomb and Canon RAW
(cr2) files.

I am using Ubuntu 8.04 with libextractor version v0.5.18a.

When I run the "extract" command on a typical cr2 file, I get the following:

> extract IMG_0986.CR2 
software - 2009:01:23 13:14:20
software - Canon EOS DIGITAL REBEL XSi
size - 2256x1504
mimetype - image/tiff

Note that the "software" keyword is duplicated and includes both the
date/time and the camera model.

Unfortunately, Mediatomb doesn't handle the duplicate keyword very well. It
stores the camera model and ignores the date.

I am a programmer, and I was considering developing my own libextractor
plug-in for cr2 files using libexiv2 to solve this problem. Before going
down that path, can you suggest an easier way?

Thanks for the help!
