NAME
     xcmap - displays the default colormap on X11 displays

SYNTAX
     xcmap [ [-d] display] [ [-g] geometry]

DESCRIPTION
     xcmap is an X11 program that displays the contents of the colormap on 4, 6,
     and  8-bit  PseudoColor  (or  GreyScale)  displays.   It displays a grid of
     squares, (4x4, 8x8, or 16x16 grid, depending on the number of planes)  that
     correspond  to  entries in the colormap.  The squares are (of course) drawn
     in their corresponding color.

     You may click (with the left button) on any of  these  squares.   Doing  so
     will  display  the  pixel number corresponding to that square, and its red,
     green, and blue components (as 4-digit hex numbers).  It will  continue  to
     do this as long as you hold the button down.

BUGS
     This  program  only  works on colormapped displays (PseudoColor, GreyScale,
     StaticColor, and StaticGrey visuals).  Running it on a display that  has  a
     default  visual  type  of	'TrueColor'  or 'DirectColor' will do nothing of
     value, and may or may not work at all.

     Also, this program only works on 4, 6, and 8-bit displays.  Period.
