+# The following functionality can be set by setting incoming variables.
+# The variable $(LEVEL) *must* be set:
#
# 1. LEVEL - The level of the current subdirectory from the top of the
# MagicStats view. This level should be expressed as a path, for
# example, ../.. for two levels deep.
#
# 2. DIRS - A list of subdirectories to be built. Fake targets are set up
-# so that each of the targets "all", "install", and "clean" each build.
-# the subdirectories before the local target.
+# so that each of the targets "all", "install", and "clean" each build
+# the subdirectories before the local target. DIRS are guaranteed to be
+# built in order.

-# 3. Source - If specified, this sets the source code filenames. If this
+# 3. PARALLEL_DIRS - A list of subdirectories to be built, but that may be
+# built in any order. All DIRS are built in order before PARALLEL_DIRS are
+# built, which are then built in any order.
+#
+# 4. Source - If specified, this sets the source code filenames. If this
# is not set, it defaults to be all of the .cpp, .c, .y, and .l files
# in the current directory. Also, if you want to build files in addition
# to the local files, you can use the ExtraSource variable
