 # This script will take an HTML compatible hex colour string and turn it into
 # a terminal sequence for true colour and other formats which best approximate
 # its colour value.
+#
+# After that, we can map a few other special named symbols.  The idea is to
+# permit shell variables such as `aaffcc bold italic` to indicate what you
+# want a format to look like.
+#
+# TODO: Update the script to allow for `bg:ff00ff` style descriptions, instead
+# of positional.
