From the man page:

     NAME
	  icol - Interpolated Color Map	Editor

     SYNOPSIS
	  icol [ -toolkit_option ] [ -option ] [ colormap_file ]

     DESCRIPTION
          Icol is an interactive tool for sketching and modifying
          color maps that are interpolated between key points. Color
          maps are often used to create images from arrays of scalar
          data, such as temperature, density or stress.  Icol can
          assign colors to key values and interpolate in several color
          spaces.  Icol can also edit maps of different lengths.


To build:

1) Read the top of the Imakefile.
2) 'make man', read the man page!
3) Change the default file format in 'Icol' if needed.
4) 'xmkmf'
5) 'make'

The icol source uses Motif widgets, but not uil (God forbid... ;-) ).
The source uses C prototypes, so you will need to compile with an ansi
C compiler (e.g.  gcc) or something close (e.g. MIPS).

A handy function prototyper, mkproto (altered slightly by myself to
dress up the output) was used to generate part of the header files.  
I use mkproto and the shell script 'protize'.  The source for mkproto
and protize is in the ../util directory.

I would like to dedicate 'icol' to the eradication of ugly colorbars.
I'm talking about those full saturation blue-to-red color bars we have
all used in our first visualizations.  Time to move on! :) :)
