Overview
========

The art-build-scripts are part of a stable/tip checkout. All scripts work for both Tip and Stable.
The scripts follow the Google Shell Style Guide, plus following additions:

 * All scripts use set -o nounset (done by default in utils.sh).
 * Constant variables used in the same script are in **lower_case**.
 * Constant variables used across scripts or picked up from environment are in **UPPER_CASE**.


Requirements
============
 1. bash 4.2+

Note: you don't need to have shellcheck installed, presubmit.sh will download it if necessary.


Guidelines
==========

 * All executable scripts should have a `main()` function.
 * All executable scripts should take options (at least -h and -v) in `arguments_parser()`.
 * All executable scripts have a `usage()` (-h or --help) that tells how the script should be used.
 * All helper scripts are not executable.
 * All scripts should include at least utils.sh, which
   * sets global shell options like set -o nounset and,
   * enables coloured logging for interactive sessions (not jenkins).
 * All scripts and changes should be checked by running ./presubmit.sh.
