+namespace EscapeSequenceProcessing { // move these out of global namespace
+
+// This chunk of code does parsing of the escape sequences sent by various Linux
+// terminals.
+//
+// It handles arrow keys, Home, End and Delete keys by interpreting the
+// sequences sent by
+// gnome terminal, xterm, rxvt, konsole, aterm and yakuake including the Alt and
+// Ctrl key
+// combinations that are understood by replxx.
+//
+// The parsing uses tables, a bunch of intermediate dispatch routines and a
+// doDispatch
+// loop that reads the tables and sends control to "deeper" routines to continue
+// the
+// parsing.	The starting call to doDispatch( c, initialDispatch ) will
+// eventually return
+// either a character (with optional CTRL and META bits set), or -1 if parsing
+// fails, or
+// zero if an attempt to read from the keyboard fails.
+//
+// This is rather sloppy escape sequence processing, since we're not paying
+// attention to what the
+// actual TERM is set to and are processing all key sequences for all terminals,
+// but it works with
+// the most common keystrokes on the most common terminals.	It's intricate, but
+// the nested 'if'
+// statements required to do it directly would be worse.	This way has the
+// advantage of allowing
+// changes and extensions without having to touch a lot of code.

+// This dispatch routine is given a dispatch table and then farms work out to
+// routines
+// listed in the table based on the character it is called with.	The dispatch
+// routines can
+// read more input characters to decide what should eventually be returned.
+// Eventually,
+// a called routine returns either a character or -1 to indicate parsing
+// failure.
