This directory contains some external programs used by Dust.
They are:
 24toppm (by A.J. Brouwer)
 ilbmtoppm (taken from the Netpbm-package, author me unknown)

Note:
 Actually I found this programs somewhere on my harddisk. 
 Sorry, but I couldn't find the remaining readme-files or 
 some other additional information about these programs.
 If you (the author of such an program) don't agree with this
 way of distributing your work please contact me.
 If I had the time I would write my own converters - maybe
 in Dust3.
