+
+How to use pktdef.h:
+
+1. Include wintab.h
+2. if using just one packet format:
+	a. Define PACKETDATA and PACKETMODE as or'ed combinations of WTPKT bits
+	   (use the PK_* identifiers).
+	b. Include pktdef.h.
+	c. The generated structure typedef will be called PACKET.  Use PACKETDATA
+	   and PACKETMODE to fill in the LOGCONTEXT structure.
+3. If using multiple packet formats, for each one:
+	a. Define PACKETNAME. Its text value will be a prefix for this packet's
+	   parameters and names.
+	b. Define <PACKETNAME>PACKETDATA and <PACKETNAME>PACKETMODE similar to
+	   2.a. above.
+	c. Include pktdef.h.
+	d. The generated structure typedef will be called
+	   <PACKETNAME>PACKET. Compare with 2.c. above and example #2 below.
+4. If using extension packet data, do the following additional steps
+   for each extension:
+	a. Before including pktdef.h, define <PACKETNAME>PACKET<EXTENSION>
+	   as either PKEXT_ABSOLUTE or PKEXT_RELATIVE.
+	b. The generated structure typedef will contain a field for the
+	   extension data.
+	c. Scan the WTI_EXTENSION categories to find the extension's
+	   packet mask bit.
+	d. OR the packet mask bit with <PACKETNAME>PACKETDATA and use the
+	   result in the lcPktData field of the LOGCONTEXT structure.
+	e. If <PACKETNAME>PACKET<EXTENSION> was PKEXT_RELATIVE, OR the
+	   packet mask bit with <PACKETNAME>PACKETMODE and use the result
+	   in the lcPktMode field of the LOGCONTEXT structure.
+
+
+Example #1.	-- single packet format
+
+#include <wintab.h>
+#define PACKETDATA	PK_X | PK_Y | PK_BUTTONS	/@ x, y, buttons @/
+#define PACKETMODE	PK_BUTTONS					/@ buttons relative mode @/
+#include <pktdef.h>
+...
+	lc.lcPktData = PACKETDATA;
+	lc.lcPktMode = PACKETMODE;
+
+Example #2. -- multiple formats
+
+#include <wintab.h>
+#define PACKETNAME		MOE
+#define MOEPACKETDATA	PK_X | PK_Y | PK_BUTTONS	/@ x, y, buttons @/
+#define MOEPACKETMODE	PK_BUTTONS					/@ buttons relative mode @/
+#include <pktdef.h>
+#define PACKETNAME		LARRY
+#define LARRYPACKETDATA	PK_Y | PK_Z | PK_BUTTONS	/@ y, z, buttons @/
+#define LARRYPACKETMODE	PK_BUTTONS					/@ buttons relative mode @/
+#include <pktdef.h>
+#define PACKETNAME		CURLY
+#define CURLYPACKETDATA	PK_X | PK_Z | PK_BUTTONS	/@ x, z, buttons @/
+#define CURLYPACKETMODE	PK_BUTTONS					/@ buttons relative mode @/
+#include <pktdef.h>
+...
+	lcMOE.lcPktData = MOEPACKETDATA;
+	lcMOE.lcPktMode = MOEPACKETMODE;
+...
+	lcLARRY.lcPktData = LARRYPACKETDATA;
+	lcLARRY.lcPktMode = LARRYPACKETMODE;
+...
+	lcCURLY.lcPktData = CURLYPACKETDATA;
+	lcCURLY.lcPktMode = CURLYPACKETMODE;
+
+Example #3. -- extension packet data "XFOO".
+	
+#include <wintab.h>
+#define PACKETDATA	PK_X | PK_Y | PK_BUTTONS	/@ x, y, buttons @/
+#define PACKETMODE	PK_BUTTONS					/@ buttons relative mode @/
+#define PACKETXFOO	PKEXT_ABSOLUTE				/@ XFOO absolute mode @/
+#include <pktdef.h>
+...
+UINT ScanExts(UINT wTag)
+{
+	UINT i;
+	UINT wScanTag;
+
+	/@ scan for wTag's info category. @/
+	for (i = 0; WTInfo(WTI_EXTENSIONS + i, EXT_TAG, &wScanTag); i++) {
+		 if (wTag == wScanTag) {
+			/@ return category offset from WTI_EXTENSIONS. @/
+			return i;
+		}
+	}
+	/@ return error code. @/
+	return 0xFFFF;
+}
+...
+	lc.lcPktData = PACKETDATA;
+	lc.lcPktMode = PACKETMODE;
+#ifdef PACKETXFOO
+	categoryXFOO = ScanExts(WTX_XFOO);
+	WTInfo(WTI_EXTENSIONS + categoryXFOO, EXT_MASK, &maskXFOO);
+	lc.lcPktData |= maskXFOO;
+#if PACKETXFOO == PKEXT_RELATIVE
+	lc.lcPktMode |= maskXFOO;
+#endif
+#endif
