# 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.
