Oops, bad Evolution (even if I did use insert->text file for the patch).
Going back to mutt. Sorry about this.
Changelog:
* CodingStyle fixes
* open counter replaced by a binary flag
* udev hacks are no longer necessary with a patched
synaptics, update the documentation

+Apple Touchpad Driver (appletouch)
+----------------------------------
+ Copyright (C) 2005 Stelian Pop <[EMAIL PROTECTED]>
+
+appletouch is a Linux kernel driver for the USB touchpad found on post
+February 2005 Apple Alu Powerbooks.
+
+This driver is derived from Johannes Berg's appletrackpad driver[1], but it has
+been improved in some areas:
+ * appletouch is a full kernel driver, no userspace program is necessary
+ * appletouch can be interfaced with the synaptics X11 driver, in order
+ to have touchpad acceleration, scrolling, etc.
+
+Credits go to Johannes Berg for reverse-engineering the touchpad protocol,
+Frank Arnold for further improvements, and Alex Harper for some additional
+information about the inner workings of the touchpad sensors.
+
+Usage:
+------
+
+In order to use the touchpad in the basic mode, compile the driver and load
+the module. A new input device will be detected and you will be able to read
+the mouse data from /dev/input/mice (using gpm, or X11).
+
+In X11, you can configure the touchpad to use the synaptics X11 driver, which
+will give additional functionalities, like acceleration, scrolling etc. In
+order to do this, make sure you're using a recent version of the synaptics
+driver (tested with 0.14.2, available from [2]), and configure a new input
+device in your X11 configuration file (take a look below for an example). For
+additional configuration, see the synaptics driver documentation.
+
+ Section "InputDevice"
+ Identifier "Synaptics Touchpad"
+ Driver "synaptics"
+ Option "SendCoreEvents" "true"
+ Option "Device" "/dev/input/mice"
+ Option "Protocol" "auto-dev"
+ Option "LeftEdge" "0"
+ Option "RightEdge" "850"
+ Option "TopEdge" "0"

+ Option "FingerLow" "55"
+ Option "FingerHigh" "60"
+ Option "MaxTapMove" "20"
+ Option "MaxTapTime" "100"
+ Option "HorizScrollDelta" "0"
+ Option "VertScrollDelta" "30"
+ Option "SHMConfig" "on"
+ EndSection
+
+ Section "ServerLayout"
+ ...
+ InputDevice "Mouse"
+ InputDevice "Synaptics Touchpad"
+ ...
+ EndSection
+
+Fuzz problems:
+--------------
+
+The touchpad sensors are very sensitive to heat, and will generate a lot of
+noise when the temperature changes. This is especially true when you power-on
+the laptop for the first time.
+
+The appletouch driver tries to handle this noise and auto adapt itself, but it
+is not perfect. If finger movements are not recognized anymore, try reloading
+the driver.
+
+You can activate debugging using the 'debug' module parameter. A value of 0
+deactivates any debugging, 1 activates tracing of invalid samples, 2 activates
+full tracing (each sample is being traced):
+ modprobe appletouch debug=1
+ or
+ echo "1" > /sys/module/appletouch/parameters/debug
