*.cpt files under Linux

Hello, I seem to have a collection of *.cpt files, probably coral paint I think. Is there any way of being able to access this files without buying a copy of coral paint (which may or may not even work)? Doing a web search seems to suggest that the best solution is to convert them in coral paint. It seems even gimp doesn't support *.cpt files. I suspect the files aren't really very important, however. So not worth going to considerable measures to recover them. Thanks -- Brian May <brian@microcomaustralia.com.au>
