#  repo sync .
#  repo start merge .
#  git merge aosp/upstream-master --no-ff # resolve any conflicts
#  ./configure && make
#  mm -j32
#  # (Make any necessary Android.mk changes and test the new strace.)

#  git commit -a --amend

# We don't currently have a good solution for the 'configure' side of things.
