+# lircd_helper
+#
+# This script can be used by udev to start or stop lircd when a remote control
+# device is added or removed.
+#
+# lircd_helper configures lircd to output using a uinput event device so that
+# eventlircd can aggregate the outputs into a single lircd socket.
+#
+# lircd_helper configures lircd to use an lircd socket name that is derived
+# from the device name. In addition, lircd_helper creates symbolic links to this
+# lircd socket that are derived from the device symbolic links. You can use this
+# socket and the symbolic link to this socket when using commands such as
+# irsend.
+#
+# lircd_helper understands two lircd_helper specific device properites set
+# using ENV{} and passed as environment variables:
+#   lircd_driver:
+#     Used to tell lircd_helper the name of the lircd driver.
+#   lircd_conf:
+#     Used to tell lircd_helper the path to the lircd.conf file to use.
