* \section Sec_CDEFS The CDEFS Parameter
* \section Sec_OPTIMIZATION The OPTIMIZATION Parameter
* Many applications have features which can be controlled by the defining of specially named preprocessor tokens at the point of compilation - for example,
* This parameter indicates the level of optimization to use when compiling the application. This will allow you to compile with an optimization level
* an application might use a compile time token to turn on or off optional or mutually exclusive portions of code. Preprocessor tokens can be
* supported by GCC, from <tt>0</tt> (no optimization) to <tt>3</tt> (fastest runtime optimization) or <tt>s</tt> (smallest size).
* defined here by listing each one with the -D command line switch, and each token can optionally be defined to a specific value. When defined in the
* project makefile, these behave as if they were defined in every source file via a normal preprocessor define statement.
*
*
* Most applications will actually have multiple CDEF lines, which are concatenated together with the "+=" operator. This ensures that large
* \section Sec_TARGET The TARGET Parameter
* numbers of configuration options remain readable by splitting up groups of options into separate lines.
* This parameter indicates the application target name, which is used as the base filename for the build binary and debugging files. This will be the
* name of the output files once linked together into the final application, ready to load into the target.
*
* \section Sec_SRC The SRC Parameter
* This parameter indicates the source files used to compile the application, as a list of C (<tt>*.c</tt>), C++ (<tt>*.cpp</tt>) and Assembly (<tt>*.S</tt>) files. Note that
* all assembly files must end in a <b>capital</b> .S extension, as lowercase .s files are reserved for GCC intermediate files.
*
*

* \section Sec_LUFA_PATH The LUFA_PATH Parameter
* As each LUFA program requires the LUFA library source code to compile correctly, the application must know where the LUFA library is located. This

* This value is similar to the CDEFS parameter listed elsewhere -- indeed, it is simply a convenient place to group LUFA related tokens away from the
