# To update:

#  git remote add toybox https://github.com/landley/toybox.git
#  git fetch toybox
#  git merge toybox/master
#  mm -j32
#  # (Make any necessary Android.mk changes and test the new toybox.)
#  repo upload .
#  git push aosp HEAD:refs/for/master  # Push to gerrit for review.
#  git push aosp HEAD:master  # Push directly, avoiding gerrit.
#
#  # Now commit any necessary Android.mk changes like normal:
#  repo start post-sync .
#  git commit -a

# To add a toy:
#

#  make menuconfig
#  # (Select the toy you want to add.)
#  make clean && make  # Regenerate the generated files.
#  # Edit LOCAL_SRC_FILES below to add the toy.
#  # If you just want to use it as "toybox x" rather than "x", you can stop now.
#  # If you want this toy to have a symbolic link in /system/bin, add the toy to ALL_TOOLS.
