 		  <MODE>: debug/fast/small.
-		    debug = -O0
-		    fast  = -O3
-		    small = -Os
-		
-		  <MCU>: f1hd/f1cle/f1mdvl/f051/f4.

-			f030   = STM32F030 series.

-		  <HSE>:
-		    Your external oscillator speed in Hz. Some of the ST standard peripheral
-		    library code uses the HSE_VALUE #define that we set here. If you're using
-		    the HSI and don't have an HSE connected then just supply a default
-		    of 8000000.

-		        Optional flag for an F4 build that will cause the hardware FPU to be
-		        used for floating point operations. Requires the "GNU Tools for ARM Embedded
-		        Processors" toolchain. Will not work with Code Sourcery Lite.

-		  Examples:
-		    scons mode=debug mcu=f1hd hse=8000000                       // debug / f1hd / 8MHz
-		    scons mode=debug mcu=f1cle hse=25000000                     // debug / f1cle / 25MHz
-		    scons mode=debug mcu=f1mdvl hse=8000000                     // debug / f1mdvl / 8MHz
-		    scons mode=fast mcu=f1hd hse=8000000 install                // fast / f1hd / 8MHz
-		    scons mode=small mcu=f4 hse=8000000 -j4 float=hard install  // small / f4 / 8Mhz
-		    scons mode=debug mcu=f4 hse=8000000 -j4 install             // debug / f4 / 8Mhz
-		    scons mode=debug mcu=f051 hse=8000000 -j4 install           // debug / f051 / 8Mhz
-		
-		  Additional Notes:
-		    The -j<N> option can be passed to scons to do a parallel build. On a multicore
-		    CPU this can greatly accelerate the build. Set <N> to approximately the number
-		    of cores that you have.
-		
-		    The built library will be placed in the stm32plus/build subdirectory.
-		
-		    If you specify the install command-line option then that library will be installed
-		    into the location given by INSTALLDIR, which defaults to /usr/local/arm-none-eabi.
-		    The library, headers, and examples will be installed respectively, to the lib,
-		    include, and bin subdirectories of INSTALLDIR.
-		
-		    It is safe to compile multiple combinations of mode/mcu/hse as the compiled object
-		    code and library are placed in a unique directory name underneath stm32plus/build.
-		    It is likewise safe to install multiple versions of the library and examples.

 The `-j<N>` option can be passed to scons to do a parallel build. On a multicore CPU this can greatly accelerate the build. Set <N> to approximately the number of cores that you have.
