# Test of Tk::ROTextANSIColor
#  This test requires that Tk widgets can be opened
#  This test will launch a Tk widget and write to it using
#  ANSI color codes. Unfortunately, it can not check that the
#  codes were displayed correctly......

# Also tests the tied version

#  In order to do this it simply keeps the window up for a few seconds
#  in case anyone needs to look at it
