	I just looked on my hardrive, that's it. It comes as two shell
applications, "cjpeg" (compress) and "djpeg" (decode). The former will 
move the following formats into JPEG: PPM, PGM, BMP, GIF, Targa and RLE.
It would require two steps and one of the desktop programs I mentioned
before to convert Super-Hi-Res into JPEG (ie, SHR->GIF->JPEG), though
I don't see any real advantage or reason for doing so.
