+# Rudmentary script for generating smali files from a Java file
+# compiled with both javac/dx and jack.
+
+# This requires a Android checkout in $HOME/android/master with the
+# art host test tools build:
+#
+# source build/envsetup.sh
+# lunch <some configuration, e.g. aosp_bullhead-userdebug>
+# m -j30 test-art-host
+#
+# It also requires a checkout of https://github.com/JesusFreke/smali
+# in $HOME/smali build by running "gradle build" in that directory.
+#
+# The output from javac/dx is placed in classes_dx, and the output from
+# Jack is placed in classes_jack.
