-# The traditional Mozilla build system relied on going through the entire
-# build tree a number of times with different targets, and many of the
-# things happening at each step required other things happening in previous
-# steps without any documentation of those dependencies.
-#
-# This build system establishes what files or operations are needed for the
-# build, and applying the necessary rules to have those in place, relying on
-# make dependencies to get them going.
-#
-# Only non-compiled parts of the application and platform are built and
-# supported here (a few other things are also left out).
-#
-# This file contains rules and dependencies to get things working. The intent
-# is for a Makefile to define some dependencies and variables, and include
-# this file. What needs to be defined there, and ends up being generated by
-# python/mozbuild/mozbuild/backend/fastermake.py is the following:
-# - TOPSRCDIR/TOPOBJDIR, respectively the top source directory and the top
-#   object directory
-# - PYTHON, the path to the python executable
-# - ACDEFINES, which contains a set of -Dvar=name to be used during
-#   preprocessing
-# - INSTALL_MANIFESTS, which defines the list of base directories handled
-#   by install manifests, see further below
-#
-# A convention used between this file and the Makefile including it is that
-# global Make variables names are uppercase, while "local" Make variables
-# applied to specific targets are lowercase.
