-For this section you'll want to have knowledge of
-.B glob (7)
-and our evil
-.B "BIT MATCHING SPECIFICATION"
-stuff.
-.PP
 The following driver 
 .B Options
-control what devices are accepted:
-
+are supported:
 .TP 7
 .BI "Option \*qDevice\*q \*q" string \*q
-Specifies the device note through which the device can be accessed.
-At this time ONLY
-.RI /dev/input/event n ,
-where
-.I n
-is an integer, are matched against this this field.
-.fi
-This option uses globbing.
-.fi
-Please note that use of this option is strongly discouraged.
-
+Specifies the device through which the device can be accessed.  This will 
+generally be of the form \*q/dev/input/eventX\*q, where X is some integer.
+The mapping from device node to hardware is system-dependent.
 .TP 7
-.BI "Option \*qName\*q \*q" string \*q
-Specifies the device name for the device you wish to use.
-.fi
-The device name is generally the only consistent identifier for devices 
-that are commonly unplugged and plugged back into different ports.
-.fi
-A list of currently plugged in devices and associated device names can be 
-obtained by typing \*qcat /proc/bus/input/devices\*q, the \*qName\*q field 
-is the value you want for this option.
-.fi
-This option uses globbing.
-
+.BI "Option \*qEmulate3Buttons\*q \*q" boolean \*q
+Enable/disable the emulation of the third (middle) mouse button for mice
+which only have two physical buttons.  The third button is emulated by
+pressing both buttons simultaneously.  Default: on, until a middle mouse
+button event is registered. Property: "Evdev Middle Button Emulation".
 .TP 7
-.BI "Option \*qPhys\*q \*q" string \*q
-Specifies the device phys string for the device you wish to use.
-.fi
-The phys string is generally consistent to the USB port a device is plugged 
-into.
-.fi
-A list of currently plugged in devices and associated device names can be 
-obtained by typing \*qcat /proc/bus/input/devices\*q, the \*qPhys\*q field 
-is the value you want for this option.
-.fi
-This option uses globbing.
-
+.BI "Option \*qEmulate3Timeout\*q \*q" integer \*q
+Sets the timeout (in milliseconds) that the driver waits before deciding
+if two buttons where pressed "simultaneously" when 3 button emulation is
+enabled.  Default: 50. Property: "Evdev Middle Button Timeout".
 .TP 7
-.BI "Option \*q" map "Bits\*q \*q" "bit specifier" \*q
-Specifies device capability bits which must be set, possibly set, or unset.
-.fi
-.IR map "Bits: Where " map
-is one of
-.BR ev ", " key ", " rel ", " abs ,
-.BR msc ", " led ", " snd ", or " ff .
-.fi
-The bit specifier format is a string consisting of
-.RI + n ", \-" n ", and ~" n
-space-separated specifiers, where
-.I n
-is a positive integer or integer range.  (The latter given in the format of 2\-6.)
-.fi
-+ specifies bits which must be set.
-.fi
-\- specifies bits which must not be set.
-.fi
-~ is a little more complex, it specifies that at least one of the bits given
-with ~ for the field in question must be set, but it doesn't matter how many
-or which of the bits. (It is actually the most useful of the 3 specifiers.)
-.fi
-As an example, \*q+0 +3 \-1\-2 ~5\-10\*q requires bits 0 and 3 be set,
-bits 1 and 2 to not be set, and at least one bit in the range of 5 to
-10 be set.
-.fi
-An annoyingly formatted set of bitmasks for your devices can be obtained
-by typing \*qcat /proc/bus/input/devices\*q, and
-.B /usr/include/linux/input.h
-should contain the defines which declare what bits are what for each field.
-
+.BI "Option \*qButtonMapping\*q \*q" string \*q
+Sets the button mapping for this device. The mapping is a space-separated list
+of button mappings that correspond in order to the physical buttons on the
+device (i.e. the first number is the mapping for button 1, etc.). The default
+mapping is "1 2 3 ... 32". A mapping of 0 deactivates the button. Multiple
+buttons can have the same mapping.
+For example, a left-handed mouse with deactivated scroll-wheel would use a
+mapping of "3 2 1 0 0". Invalid mappings are ignored and the default mapping
+is used. Buttons not specified in the user's mapping use the default mapping.
 .TP 7
-.BI "Option \*qbustype\*q \*q" n \*q
-Specifies the bus ID for the device you wish to use.
-.fi
-This is either 0 (the default, matches anything), or the
-.BI Bus= n
-field in
-.B /proc/bus/input/devices
-for your device.
-.fi
-This value depends on what type of bus your device is connected to.
-
+.BI "Option \*qDragLockButtons\*q \*q" "L1 B2 L3 B4" \*q
+Sets \*qdrag lock buttons\*q that simulate holding a button down, so
+that low dexterity people do not have to hold a button down at the
+same time they move a mouse cursor. Button numbers occur in pairs,
+with the lock button number occurring first, followed by the button
+number that is the target of the lock button. Property: "Evdev
+Drag Lock Buttons".
 .TP 7
-.BI "Option \*qvendor\*q \*q" n \*q
-Specifies the vendor ID for the device you wish to use.
-.fi
-This is either 0 (the default, matches anything), or the
-.BI Vendor= n
-field in
-.B /proc/bus/input/devices
-for your device.
-.fi
-This value should remain constant barring perhaps firmware updates to the
-device itself.
-
+.BI "Option \*qDragLockButtons\*q \*q" "M1" \*q
+Sets a \*qmaster drag lock button\*q that acts as a \*qMeta Key\*q
+indicating that the next button pressed is to be
+\*qdrag locked\*q. Property: "Evdev Drag Lock Buttons".
 .TP 7
-.BI "Option \*qversion\*q \*q" n \*q
-Specifies the version for the device you wish to use.
-.fi
-This is either 0 (the default, matches anything), or the
-.BI Version= n
-field in
-.B /proc/bus/input/devices
-for your device.
-.fi
-This value should remain constant barring perhaps firmware updates to the
-device itself.
-
-.TP 7
-.BI "Option \*qproduct\*q \*q" n \*q
-Specifies the product ID for the device you wish to use.
-.fi
-This is either 0 (the default, matches anything), or the
-.BI Product= n
-field in
-.B /proc/bus/input/devices
-for your device.
-.fi
-This value should remain constant barring perhaps firmware updates to the
-device itself.
-
-.TP 7
-.BI "Option \*qPass\*q \*q" n \*q
-Specifies the order in which evdev will scan for devices.
-.fi
-This is in the range of 0 to 3, and is used for the case
-where more then one evdev input section matches the same device.
-.fi
-An input section with a lower pass number will always beat out
-one with a higher pass number.  Order when both sections are
-the same number is undefined.
-.fi
-The default is 0.
-
-
-.PP
-.SS RELATIVE AXIS CONFIGURATION
-The relative axis portion of this driver handle all reported relative axes.
-.fi
-The axes are named X, Y, Z, RX, RY, RZ, HWHEEL, DIAL, WHEEL, MISC, 10, 11,
-12, 13, 14, and 15.
-.fi
-The axes are reported to X as valuators, with the default mapping of axes
-to valuators being the first axes found to the first valuator, the second
-found to the second valuator, and so on, so that if you have axes X, Y,
-HWHEEL, and WHEEL, you would have X=0, Y=1, HWHEEL=2, WHEEL=3.
-.fi
-If the driver is reporting core events, valuators 0 and 1 are always mapped
-to x and y coordinates, respectively.
-.fi
-The following driver 
-.B Options
-control the relative axis portion of the driver:
-.TP 7
-.BI "Option \*q" axis "RelativeAxisMap\*q \*q" n \*q
-This remaps the axis specified to the specified valuator.
-.TP 7
-.BI "Option \*q" axis "RelativeAxisButtons\*q \*q" "n n" \*q
-This remaps the axis specified to the specified buttons.
-.fi
-Note that the physical buttons are always remapped around \*qfake\*q buttons
-created by this option, so that if you have physical buttons 1 2 3 4 5,
-and map the Wheel axis to buttons 4 5, you get buttons 1 2 3
-.B 4 5
-6 7, with buttons 6 and 7 being physical buttons 4 and 5.
-.PP
-.SS ABSOLUTE AXIS CONFIGURATION
-The relative axis portion of this driver handle all reported relative axes.
-.fi
-The axes are named X, Y, Z, RX, RY, RZ, THROTTLE, RUDDER, WHEEL, GAS, BRAKE,
-<11\-15>, HAT0X, HAT0Y, HAT1X, HAT1Y, HAT2X, HAT2Y, HAT3X, HAT3Y, PRESSURE,
-TILT_X, TILT_Y, TOOL_WIDTH, VOLUME, <29\-39>, MISC, <41\-62>.
-.fi
-The axes are reported to X as valuators, with the default mapping of axes
-to valuators being the first axes found to the first valuator, the second
-found to the second valuator, and so on, so that if you have axes X, Y,
-TILT_X, and TILT_Y, you would have X=0, Y=1, TILT_X=2, TILT_Y=3.
-.fi
-If the driver is reporting core events, valuators 0 and 1 are always mapped
-to x and y coordinates, respectively.
-.fi
-The following driver 
-.B Options
-control the relative axis portion of the driver:
-.TP 7
-.BI "Option \*q" axis "AbsoluteAxisMap\*q \*q" n \*q
-This remaps the axis specified to the specified valuator.
-.TP 7
-.BI "Option \*qAbsoluteScreen\*q \*q" n \*q
-This binds the device to a specific screen, scaling it to
-the coordinate space of that screen.
-.fi
-The number can either be \-1, or a valid screen number.
-.fi
-If \-1 or if in relative mode no scaling or screen fixing is done.
-.fi
-This is of most use for digitizers, where the screen and the input
-device are the same surface.
-.TP 7
-.BI "Option \*qMode\*q \*q" mode \*q
-This selects the default mode for the device.
-.fi
-Valid values are \*qabsolute\*q and \*qrelative\*q.
-.fi
-This can be set at run time per actual device with the xinput utility.
-.PP
-.SS BUTTON CONFIGURATION
-At the moment, the button portion of this driver only handles buttons
-reported as mouse buttons, that is from BTN_MOUSE to BTN_JOYSTICK \- 1.
-.fi
-At this time there are no configuration options for buttons.
-.SS KEYBOARD CONFIGURATION
-The keyboard portion of this driver handles all keys reported and requires 
-XKB support.
-.fi
-The following driver 
-.B Options
-control the relative axis portion of the driver:

+.BI "Option \*qEmulateWheel\*q \*q" boolean \*q
+Enable/disable "wheel" emulation.  Wheel emulation means emulating button
+press/release events when the mouse is moved while a specific real button
+is pressed.  Wheel button events (typically buttons 4 and 5) are
+usually used for scrolling.  Wheel emulation is useful for getting wheel-like
+behaviour with trackballs.  It can also be useful for mice with 4 or
+more buttons but no wheel.  See the description of the
+.BR EmulateWheelButton ,
+.BR EmulateWheelInertia ,
+.BR EmulateWheelTimeout ,
+.BR XAxisMapping ,
 and

+options below.  Default: off. Property "Evdev Wheel Emulation".
 .TP 7
-.BI "Option \*qXkbModel\*q \*q" modelname \*q
-specifies the XKB keyboard model name.  Default: \*qevdev\*q.
+.BI "Option \*qEmulateWheelButton\*q \*q" integer \*q
+Specifies which button must be held down to enable wheel emulation mode.
+While this button is down, X and/or Y pointer movement will generate button
+press/release events as specified for the
+.B XAxisMapping
+and
+.B YAxisMapping
+settings.  Default: 4. Property: "Evdev Wheel Emulation Button".
 .TP 7
-.BI "Option \*qXkbLayout\*q \*q" layoutname \*q
-specifies the XKB keyboard layout name.  This is usually the country or
-language type of the keyboard.  Default: \*qus\*q.
+.BI "Option \*qEmulateWheelInertia\*q \*q" integer \*q
+Specifies how far (in pixels) the pointer must move to generate button
+press/release events in wheel emulation mode.  Default: 10. Property: "Evdev

+Specifies the time in milliseconds the
+.BR EmulateWheelButton
+must be pressed before wheel emulation is started. If the
+.BR EmulateWheelButton
+is released before this timeout, the original button press/release event
+is sent.  Default: 200. Property: "Evdev Wheel Emulation Timeout".

+ * Lets create a simple finite-state machine for 3 button emulation:
+ *
+ * We track buttons 1 and 3 (left and right).  There are 11 states:
+ *   0 ground           - initial state
+ *   1 delayed left     - left pressed, waiting for right
+ *   2 delayed right    - right pressed, waiting for left
+ *   3 pressed middle   - right and left pressed, emulated middle sent
+ *   4 pressed left     - left pressed and sent
+ *   5 pressed right    - right pressed and sent
+ *   6 released left    - left released after emulated middle
+ *   7 released right   - right released after emulated middle
+ *   8 repressed left   - left pressed after released left
+ *   9 repressed right  - right pressed after released right
+ *  10 pressed both     - both pressed, not emulating middle
+ *
+ * At each state, we need handlers for the following events
+ *   0: no buttons down
+ *   1: left button down
+ *   2: right button down
+ *   3: both buttons down
+ *   4: emulate3Timeout passed without a button change
+ * Note that button events are not deltas, they are the set of buttons being
+ * pressed now.  It's possible (ie, mouse hardware does it) to go from (eg)
+ * left down to right down without anything in between, so all cases must be
+ * handled.
+ *
+ * a handler consists of three values:
+ *   0: action1
+ *   1: action2
+ *   2: new emulation state
+ *
+ * action > 0: ButtonPress
+ * action = 0: nothing
+ * action < 0: ButtonRelease
+ *
+ * The comment preceeding each section is the current emulation state.
+ * The comments to the right are of the form
+ *      <button state> (<events>) -> <new emulation state>
+ * which should be read as
+ *      If the buttons are in <button state>, generate <events> then go to
+ *      <new emulation state>.
