[FWTools] JPEG Worldfile options

[Travis Kirstine]

Hi All
I have create several thousand jpg files from tiff \ tfw using
gdal_translate (gdal_translate -of JPEG in.tif out.jpg).  The problem
that I am now having is that the associated  .aux.xml file with
<GeoTransform> information is not recognized by older versions of gdal
/ mapserver.  Is there any utility to convert that xml info to a
worldfile without reprocessing the rasters?
