+# Udev rules for Archlinux by Tobias Powalowski <tpowa@archlinux.org>
+# do not edit this file, it will be overwritten on update
+#
+# There are a number of modifiers that are allowed to be used in some
+# of the different fields. They provide the following subsitutions:
+#
+# %n the "kernel number" of the device.
+# For example, 'sda3' has a "kernel number" of '3'
+# %k the kernel name for the device.
+# %M the kernel major number for the device
+# %m the kernel minor number for the device
+# %b the bus id for the device
+# %c the string returned by the PROGRAM
+# %s{filename} the content of a sysfs attribute.
+# %% the '%' char itself.
+#
+# There are a number of modifiers that are allowed to be used in some of the
+# fields. See the udev man page for a full description of them.
