 Options are modifiers to services.  They affect how and when init
 runs the service.
 
+console [<console>]
+  This service needs a console. The optional second parameter chooses a
+  specific console instead of the default. The default "/dev/console" can
+  be changed by setting the "androidboot.console" kernel parameter. In
+  all cases the leading "/dev/" should be omitted, so "/dev/tty0" would be
+  specified as just "console tty0".
+
 critical
   This is a device-critical service. If it exits more than four times in
   four minutes, the device will reboot into recovery mode.

+# Local unit test Makefile
+#
+# This makefile builds and runs the trusty_keymaster unit tests locally on the development
+# machine, not on an Android device.
+#
+# To build and run these tests, one pre-requisite must be manually installed: BoringSSL.
+# This Makefile expects to find BoringSSL in a directory adjacent to $ANDROID_BUILD_TOP.
+# To get and build it, first install the Ninja build tool (e.g. apt-get install
+# ninja-build), then do:
+#
+# cd $ANDROID_BUILD_TOP/..
+# git clone https://boringssl.googlesource.com/boringssl
+# cd boringssl
+# mdkir build
+# cd build
+# cmake -GNinja ..
+# ninja
+#
+# Then return to $ANDROID_BUILD_TOP/system/keymaster and run "make".
