     6 # This file sets all the make variables that allow you to customize a build.
     7 # There are 4 ways in which you can customize your build:
     8 # 1) Edit the variable assignments in this file (this is a tracked file, so your repository will be dirty)
     9 # 2) Edit the variable assignments in `Makefile.conf` (which is a tracked file, so your repository will be dirty)
    10 # 3) Create `local.conf` and fill it with variable assignments.
    11 # 4) Set the environment variable `BUILD_CONFIG` to an absolute path.
    12 #    The variable assignments found in the make file at the path indicated by `BUILD_CONFIG` will be evaluated.
    13 # Customization options are applied in the order given above. Later variable assignments take precedence over earlier ones.
    14 # It is possible to use multiple variants simultaniously.
    15 # If nothing is changed according to these 4 methods, a default configuration for your platform (specified below) will be used for the build.
