-# This Makefile provides a very generic framework of the following
-# functionalities:
-#
-# Multi-language support (currently any combination of Ada/C/C++ supported)
-# Automatic handling of source dependencies
-# Handling of various C/C++ compilers
-# Handling of Ada sources using the GNAT toolchain
-# Complete build process (compile/bind/link)
-# Individual compilation (on a file, or on a language)
-# Handling of an object directory
-
-# Here are the rules that can be used from the command line:
-#
-# build: complete compile/bind/link process
-# compile: compile all files that are not up-to-date
-# link: bind/link
-# ada: compile all Ada files that are not up-to-date
-# c: ditto for C files
-# c++: ditto for C++ files
-# <ada file>: compile the specified file if needed.
-# <object file>: compile the corresponding C/C++ source file if needed.
-# clean: remove all temporary files
-
-# This Makefile expects the following variables to be set by the caller
-# (typically another Makefile):
-#
-# ADA_SPEC extension of Ada spec files (optional, default to .ads)
-# ADA_BODY extension of Ada body files (optional, default to .adb)
-# C_EXT extension of C files (optional, default to .c)
-# CXX_EXT extension of C++ files (optional, default to .cc)
-# OBJ_EXT extension of object files (optional, default to .o)
-# SRC_DIRS blank separated list of source directories
-# C_SRCS explicit list of C sources (optional)
-# C_SRCS_DEFINED if set, indicates that C_SRCS is already set
-# CXX_SRCS explicit list of C++ sources (optional)
-# CXX_SRCS_DEFINED is set, indicates that CXX_SRCS is already set
-# OBJ_DIR a single directory where object files should be put
-# EXEC_DIR a single directory where executables should be put (optional)
-# LANGUAGES a blank separated list of languages supported, e.g "ada c"
-# the current list of recognized languages is: ada, c, c++
-# CC name of the C compiler (optional, default to gcc)
-# CXX name of the C++ compiler (optional, default to gcc)
-# AR_CMD command to create an archive (optional, default to "ar rc")
-# AR_EXT file extension of an archive (optional, default to ".a")
-# RANLIB command to generate an index (optional, default to "ranlib")
-# GNATMAKE name of the GNAT builder (optional, default to "gnatmake")
-# ADAFLAGS additional Ada compilation switches, e.g "-gnatf" (optional)
-# CFLAGS default C compilation switches, e.g "-O2 -g" (optional)
-# CXXFLAGS default C++ compilation switches (optional)
-# LIBS libraries to link with (optional)
-# LDFLAGS linker switches (optional)
-# ADA_SOURCES list of main Ada sources (optional)
-# EXEC name of the final executable (optional)
-# MAIN language of the main program (optional)
-# MAIN_OBJECT main object file (optional)
-# PROJECT_FILE name of the project file, without the .gpr extension
-# DEPS_PROJECTS list of project dependencies (optional)
-
-# SILENT (optional) when defined, make -s will not output anything
-# when all commands are successful.
-
-# Set the source search path for C and C++ if needed
