# Usage:
#   1. Get Chromium depot_tools, and put it in your path.
#      See https://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
#
#   2. From the SPIRV-Tools source tree root:
#
#      # Get additional build tooling, using the info in the DEPS file.
#      cp utils/standalone.gclient .
#      gclient sync --gclientfile=standalone.gclient
#
#   3. One of the tools downloaded in the previous step is the binary for 'gn'.
#      Put it on your path.
#
#      # This is for Linux amd64 environments:
#      PATH=$(pwd)/build/linux64:$PATH
#
#   3. Create a build tree with Ninja build recipes.
#
#      gn gen out/Debug
#
#      # Or build a release build:
#      gn gen out/Release --args="is_debug=false"
#
#   4. Use ninja to build the project
#
#      ninja -C out/Debug
