Rewrite EXIF comment into IPTC Caption-Abstract

I used to embed the captions of photos within the EXIF metadata using . It seems however that new, more flexible standards are being developed.. Google’s Picasa for instance uses the IPTC Caption-Abstract tag to write the caption information. I copied the exif comment tag to the IPTC Caption-Abstract using Phil Harvey’s ExifTool .

For example:

exiftool '-IPTC:Caption-Abstract<$Comment' test.jpg

Looks like I’ll redo it when the XMP standard takes over.
