gifcolor [-q] [-b Background] [-h] <ColorMapFile
As gifcolor can generate huge amounts of data, ^C will kill it, but 'q' will stop only the printing (of one of -e, -z, -p), while file integrity will still be checked.
Quiet mode. Defaults off on MSDOS, on under UNIX. Controls printout of running scan lines. Use -q- to invert.
Set the image's backround color to a given numeric index.
Print one line of command line help, similar to Usage above.
