13 The gplcpt program converts GIMP(1) colour palette (gpl) files to the
14 GMT(1) colour palette table (cpt) format. The output is a piecewise
15 constant (step or discrete) gradient. One could use cptcont(1) program
16 to convert the output to a continuous cpt file if so desired.
17
18 The program will read from stdin if a file is not specified as the
19 final argument, and write to stdout if the -o option is not specified.
