-# USAGE:
-# Variables that must be defined in including makefile.
-# PROJECT: Name to be given to the output binary for this project.
-# SRC: The root directory for the sources of your project.
-# GCC4MED_DIR: The root directory for where the gcc4mbed sources are located
-# in your project. This should point to the parent directory
-# of the build directory which contains this gcc4mbed.mk file.
-# LIBS_PREFIX: List of library/object files to prepend to mbed.ar capi.ar libs.
-# LIBS_SUFFIX: List of library/object files to append to mbed.ar capi.ar libs.
-# GCC4MBED_TYPE: Type of build to produce. Allowed values are:
-# Debug - Build for debugging. Disables optimizations and
-# links in debug MRI runtime. Best debugging
-# experience.
-# Release - Build for release with no debug support.
-# Checked - Release build with debug support. Due to
-# optimizations, debug experience won't be as good
-# as Debug but might be needed when bugs don't
-# reproduce in Debug builds.
-# default: Release
-# MRI_BREAK_ON_INIT: Should the program halt before calling into main(),
-# allowing the developer time to set breakpoints in main()
-# or in code run from within global constructors.
-# default: 1 - break on init.
-# MRI_SEMIHOST_STDIO: Set to non-zero value to allow debug monitor to use
-# semi-host calls to redirect stdin/stdout/stderr to the
-# gdb console.
-# default: 1 for Debug/Checked builds and 0 for Release.
-# MRI_UART: Select the UART to be used by the debugger. See mri.h for
-# allowed values.
-# default: MRI_UART_MBED_USB - Use USB based UART on the mbed.
-# Example makefile:
-# PROJECT=HelloWorld
-# SRC=.
-# GCC4MBED_DIR=../..
-# LIBS_PREFIX=../agutil/agutil.ar
-# LIBS_SUFFIX=
-#
-# include ../../build/gcc4mbed.mk
