#	@description
#	This file echoes a bunch of color codes to the terminal to demonstrate what's available.  Each
#	line is the color code of one foreground color, out of 17 (default + 16 escapes), followed by a
#	test use of that color on all nine background colors (default + 8 escapes).
#
#	Each table cell has the same text within to get a sense of comparison. This text can be
#	specified as the only parameter when calling this script. The script specifying numbers is
#	followed by another color script which does not have numbers specified.
