+# This is an example script working as Weston's calibration helper.
+# Its purpose is to permanently store the calibration matrix for the given
+# touchscreen input device into a udev property. Since this script naturally
+# runs as the user that runs Weston, it presumably cannot write directly into
+# /etc. It is left for the administrator to set up appropriate files and
+# permissions.
+
+# To use this script, one needs to edit weston.ini, in section [libinput], add:
+#   calibration_helper=/path/to/bin/calibration-helper.bash
+
+# exit immediately if any command fails
+set -e
+
+# The arguments Weston gives us:
+SYSPATH="$1"
+MATRIX="$2 $3 $4 $5 $6 $7"
+
+# Pick something to recognize the right touch device with.
+# Usually one would use something like a serial.
+SERIAL=$(udevadm info "$SYSPATH" --query=property | \
+	awk -- 'BEGIN { FS="=" } { if ($1 == "ID_SERIAL") { print $2; exit } }')
+
+# If cannot find a serial, tell the server to not use the new calibration.
+[ -z "$SERIAL" ] && exit 1
+
+# You'd have this write a file instead.
+echo "ACTION==\"add|change\",SUBSYSTEM==\"input\",ENV{ID_SERIAL}==\"$SERIAL\",ENV{LIBINPUT_CALIBRATION_MATRIX}=\"$MATRIX\""
+
+# Then you'd tell udev to reload the rules:
+#udevadm control --reload
+# This lets Weston get the new calibration if you unplug and replug the input
+# device. Instead of writing a udev rule directly, you could have a udev rule
+# with IMPORT{file}="/path/to/calibration", write
+# "LIBINPUT_CALIBRATION_MATRIX=\"$MATRIX\"" into /path/to/calibration instead,
+# and skip this reload step.
+
+# Make udev process the new rule by triggering a "change" event:
+#udevadm trigger "$SYSPATH"
+# If you were to restart Weston without rebooting, this lets it pick up the new
+# calibration.
