+// This module is designed to provide a uniform method of sending commands to
+// the board through command packets. The difficulty is, some commands take
+// parameters, others do not. Furthermore, it is often useful to send several
+// commands to the same channel as part of the same packet. (See also i2pack.h.)
+//
+// This module is designed so that the caller should not be responsible for
+// remembering the exact syntax of each command, or at least so that the
+// compiler could check things somewhat. I'll explain as we go...
+//
+// First, a structure which can embody the syntax of each type of command.

+	// The command and its parameters, which may be of arbitrary length. Don't
+	// worry yet how the parameters will be initialized; macros later take care
+	// of it. Also, don't worry about the arbitrary length issue; this structure
+	// is never used to allocate space (see i2cmd.c).
