# This Makefile provides a very generic framework of the following
# functionalities:
# 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")
+# 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)
# 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
