-Description
-    My goal in writing this script was to provide all the functionality of all
-    the various perl/sh scripts found around the web in one place with some
-    additional bells and whistles.
+                                     $f7▌$rst
 
-    It automatically detects 8, 16, 88, 256 color capabilities (via ncurses)
-    and displays the appropriate color charts. It can display the colors as
-    blocks or (2d) cubes optionally with color values overlaid in int or hex
-    values.  It can show the full rgb text string as well. It can also show the
-    display with a vertical (default) or horizontal orientation. It has the
-    option of additional padding and supports -h --help as well.
+                                   $f7▌$rst
 
-    It also works as a utility for converting between 256 and 88 color values.
-
-Development
-    A note on coding style. I was playing around with using classes as simple
-    module-esque namespaces; i.e. having classes that have all staticmethods
-    and never get instatiated. As a side effect of this it makes calls at the
-    module level thus this script is not really importable, thus limiting
-    reuse.
