>+is an __xservername__ input driver for Linux\'s generic event devices.  It
>+therefore supports all input devices that the kernel knows about, including
>+most mice and keyboards.
>+.PP
>+The 
>+.B evdev
>+driver can serve as both a pointer and a keyboard input device, and may be
>+used as both the core keyboard and the core pointer.  Multiple input devices
>+are supported by multiple instances of this driver, with one Load
>+directive for evdev in the Module section of your __xconfigfile__ for each
>+input device that will use this driver.
>+.PP
>+.SH SUPPORTED HARDWARE
>+In general, any input device that the kernel has a driver for can be accessed
>+through the 
>+.B evdev
>+driver.  See the Linux kernel documentation for a complete list.
>+.PP
>+.SH CONFIGURATION DETAILS
>+Please refer to __xconfigfile__(__filemansuffix__) for general configuration
>+details and for options that can be used with all input drivers.  This
>+section only covers configuration details specific to this driver.
>+.PP
>+.SH GENERAL OPTIONS
>+The following driver 
>+.B Options
>+control what devices are accepted, note that globbing is used in all cases:
>+.TP 7
>+.BI "Option \*qDevice\*q \*q" string \*q
>+Specifies the device note 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.
>+.fi
>+Please note that use of this option is discouraged.
>+.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.
>+.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 consistant 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.
>+.PP
>+.SH RELATIVE AXIS CONFIGURATION
>+The relative axis portion of this driver handle all reported relative axies.
>+.fi
>+The axies are named X, Y, Z, RX, RY, RZ, HWHEEL, DIAL, WHEEL, MISC, 10, 11,
>+12, 13, 14, and 15.
>+.fi
>+The axies are reported to X as valuators, with the default mapping of axies
>+to valuators being the first axies found to the first valuator, the second
>+found to the second valuator, and so on, so that if you have axies 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" number \*q
>+This remaps the axis specified to the specified valuator.
>+.TP 7
>+.BI "Option \*q<axis>RelativeAxisButtons\*q \*q" number " number\*q
>+This remaps the axis specified to the specified buttons.
>+.fi
>+Note that the physical buttons are always remapped around 'fake' 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
>+.SH 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 buttens.
>+.SH 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:
>+.TP 7
>+.BI "Option \*qXkbRules\*q \*q" rules \*q
>+specifies which XKB rules file to use for interpreting the
>+.BR XkbModel ,
>+.BR XkbLayout ,
>+.BR XkbVariant ,
>+and
>+.B XkbOptions
>+settings.  Default: "xorg" for most platforms, but "xfree98" for the
>+Japanese PC-98 platforms.
>+.TP 7
>+.BI "Option \*qXkbModel\*q \*q" modelname \*q
>+specifies the XKB keyboard model name.  Default: "evdev".
>+.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: "us".
>+.TP 7
>+.BI "Option \*qXkbVariant\*q \*q" variants \*q
>+specifies the XKB keyboard variant components.  These can be used to
>+enhance the keyboard layout details.  Default: not set.
>+.TP 7
>+.BI "Option \*qXkbOptions\*q \*q" options \*q
>+specifies the XKB keyboard option components.  These can be used to
>+enhance the keyboard behaviour.  Default: not set.
>+.PP
>+Some other XKB-related options are available, but they are incompatible
>+with the ones listed above and are not recommended, so they are not
>+documented here.
