RT_BYTE_ENCODED (run-time byte encoded) is a format used when someone
wants to save space and still have the rasterfile readyily available.
This effectively rules out compression utilities, as various programmes
like suntools-e, touch-up, screenload et al can't do the decompression
themselves. Suntools, suntools-e, screenload and screenloadc are all able
to handle RT_BYTE_ENCODING; images will appear as advertised. I don't
know if touch-up can cope with it; I haven't checked and can't until I'm
near a sun. I suspect it might not be able to since an option to save it
RT_BYTE_ENCODED does not exist in that programme.

There is one in development here and I suspect that when it is completed
it will be announced in Sun-Spots and made available via anonymous ftp.
If one already exists out there, our developers would be happy to hear
about it.
