+
+# 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 new build system tries to start afresh by establishing 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.
+#
+# As of writing, only building non-compiled parts of Firefox is supported
+# here (a few other things are also left out). This is a starting point, with
+# the intent to grow this build system to make it more complete.
+#
+# 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
+# - MOZ_CHROME_FILE_FORMAT, which defines whether to use file copies or
+#   symbolic links
+# - JAR_MN_TARGETS, which defines the targets to use for jar manifest
+#   processing, see further below
+# - PP_TARGETS, which defines the file paths of preprocessed files, see
+#   further below
+# - INSTALL_MANIFESTS, which defines the list of base directories handled
+#   by install manifests, see further below
+# - MANIFEST_TARGETS, which defines the file paths of chrome 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.

+# When processing jar manifests, relative paths given inside a jar manifest
