 # Top level makefile for building RTS services library.
 #
 # By default, the RTS library is put into a 'lib' directory under the $RTSROOT
 # directory. The user can specify an alternate location with LIBDEST=xxx.
 # The LIBDEST directory is created if it doesn't exist.
 #
 # Build products are put into BUILDROOT (default is +/build). Created by build.
 #
 # Targets:
 #     (none)        : The default target is 'all' - same as 'library'.
 #     all           : everything - currently only 'library'
 #     library       : the RTS services library
 #     clean         : Delete all build products.
 #
 # Variables should be specified during make and make clean
 # invoke with <var>=<value> or with environment variables:
 #     TARGETOS      : Target platform. (i.e. TARGETOS=linux)
 #     BUILDTOOLS    : (i.e. BUILDTOOLS=x86-gcc-4.6.3)
 #
 # Variables (can be overridden during make invoke with <var>=<value>):
 #     RTSROOT       : default RTSROOT=. : umlrt.rts repo dir.
 #     BUILDROOT     : default BUILDROOT=$(RTSROOT)/build : build output dir.
 #     CONFIG        : default CONFIG=$(TARGETOS).$(BUILDTOOLS)
 #     LIBDEST       : Change default library destination directory.
 #     DEPEND        : default DEPEND=1 : 'DEPEND=0' to skip dependency generation.
 #
 # Local variables (not typically passed in via env) are in lower-case.
 #
 # Examples:
 #   make                   : Default - same as 'make all' and 'make library'
 #   make all               : Default - same as 'make' and 'make library'
 #   make library           : Default - same as 'make' and 'make all'
 #   make DEPEND=0          : Build the library but skip building dependencies
 #   make clean             : clean all build products (library, objects, dependency files.)
 #   make LIBDEST=~/lib     : Put library into '~/lib'.
 #   make BUILDROOT=~/build : Put build-products into '~/build'.
 #
 # After a clean pull from the repo, "make DEPEND=0" will build everything but
 # will skip building dependencies (hence will be faster). (Dependencies are not
 # required for this scenario to guarantee everything gets explicitly built.)
 #
 # RTSROOT and BUILDROOT notes
 # ---------------------------
 # RTSROOT names the top-level (umlrt.rts) directory. The default RTSROOT
 # is current working directory (where this Makefile currently resides).
 #
 # BUILDROOT names the top-level build-products output directory tree.
 # Object files and dependency files are written here.
 # This directory tree is created by the build process if it doesn't yexist.
 # The tree-structure under BUILDROOT matches the associated directory tree
 # under RTSROOT.
