   --- To sync with upstream:

    # Update source and regenerate generated files.
    git remote add toybox https://github.com/landley/toybox.git
    git fetch toybox && git merge toybox/master && ./regenerate.sh

    # Make any necessary Android.bp changes and rebuild.

    # Run all the tests.
    ./run-tests-on-android.sh
    # Run a single test.
    ./run-tests-on-android.sh wc

    # Upload changes.
    git commit -a --amend
    git push aosp HEAD:refs/for/master  # Push to gerrit for review.
    git push aosp HEAD:master           # Push directly, avoiding gerrit.


   --- To add a toy:

    # Edit the three .config-* files to enable the toy you want for the targets
    # you want it on, and regenerate the generated files:
    ./post_update.sh .

    # Edit the relevant `srcs` below, depending on where the toy should be
    # available.

    # If you just want to use the toy via "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 `symlinks` below.
