+#===------------------------------------------------------------------------===#
+#
+# This file is included by all of the LLVM makefiles.  This file defines common
+# rules to do things like compile a .cpp file or generate dependency info.
+# These are platform dependent, so this is the file used to specify these
+# system dependent operations.
+#
+# 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
+#    source directory.  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.  DIRS are guaranteed to be
+#    built in order.
+#
+# 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
+#
+# 5. SourceDir - If specified, this specifies a directory that the source files
+#    are in, if they are not in the current directory.  This should include a
+#    trailing / character.
+#
+# 6. LLVM_SRC_ROOT - If specified, points to the top of the LLVM source tree.
+#
+# 8. PROJ_SRC_DIR - The directory which contains the current set of Makefiles
+#    and usually the source code too (unless SourceDir is set).
+#
+# 9. PROJ_SRC_ROOT - The root directory of the source code being compiled.
+#
+# 10. PROJ_OBJ_DIR - The directory where object code should be placed.
+#
+# 11. PROJ_OBJ_ROOT - The root directory for where object code should be
+#     placed.
+#
+# For building,
+# 	LLVM, LLVM_SRC_ROOT = PROJ_SRC_ROOT
