+ * All of the terminal control code in this library uses ANSI escape sequences (https://en.wikipedia.org/wiki/ANSI_escape_code).
+ * Instead of using termcap and curses, code can use this simpler library instead.  The simple fact is that in 2022, there's
+ * probably no terminal software that you're using that does not understand these escape sequences.  Truth be told, the
+ * termcap databases are suffering from a tremendous amount of bitrot, as no actual hardware or software in common use
+ * actually uses anything but the ANSI codes.
+ *  
+ * Some ANSI engines have a maximum limit to how many "clauses" a CSI sequence can have.  To this end, no significant effort
+ * should be put into trying to collapse the sequences for foreground and background into one SGR command.  Despite it taking
+ * a few more bytes, it's probably more portable to issue multiple commands.
