     8 # This file sets all the make variables that allow you to customize a build.
     9 # There are 3 ways in which you can customize your build:
    10 # 1) Edit the variable assignments in this file (this is a tracked file, so your repository will be dirty)
    11 # 2) Create `local.conf` and fill it with variable assignments.
    12 # 3) Set the environment variable `BUILD_CONFIG` to an absolute path.
    13 #    The variable assignments found in the make file at the path indicated by `BUILD_CONFIG` will be evaluated.
    14 # Customization options are applied in the order given above. Later variable assignments take precedence over earlier ones.
    15 # It is possible to use multiple variants simultaniously.
    16 # If nothing is changed according to these 3 methods, a default configuration for your platform (specified below) will be used for the build.
