Feed it a color map file (as generated, say, by the \-s option of gifclrmp) and it will generate a GIF containing lines of the form\&. .sp .if n \{\ .RS 4 .\} .nf Color %\-3d: [%\-3d, %\-3d, %\-3d]: .fi .if n \{\ .RE .\} .PP where the first number is the zero\-based color index, and the triple is the index\*(Aqs [Red, Green, Blue] value\&. There will be one such line for each color\&. Each line will be set in a simple 8x8 font in the color it describes; thus, any lines corresponding to the GIF\*(Aqs background color will be blank\&. .SH "OPTIONS" .PP \-v .RS 4 Verbose mode (show progress)\&.
