* This parameter indicates the raw input clock frequency to the USB module within the microcontroller in Hz. This may be very different on some platforms
* to the main CPU clock or other peripheral/bus clocks.
*
- * \section Sec_CDEFS The CDEFS Parameter
- * Many applications have features which can be controlled by the defining of specially named preprocessor tokens at the point of compilation - for example,
- * an application might use a compile time token to turn on or off optional or mutually exclusive portions of code. Preprocessor tokens can be
- * 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.
+ * \section Sec_OPTIMIZATION The OPTIMIZATION Parameter
+ * This parameter indicates the level of optimization to use when compiling the application. This will allow you to compile with an optimization level
+ * supported by GCC, from <tt>0</tt> (no optimization) to <tt>3</tt> (fastest runtime optimization) or <tt>s</tt> (smallest size).
*
- * Most applications will actually have multiple CDEF lines, which are concatenated together with the "+=" operator. This ensures that large
- * numbers of configuration options remain readable by splitting up groups of options into separate lines.
+ * \section Sec_TARGET The TARGET Parameter
+ * 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
- * value specifies the path to the LUFA library base relative to the path of the project makefile.
- *
- * \section Sec_LUFA_OPTS The LUFA_OPTS Parameter
- * 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
- * application's compile time tokens. Normally, these options do not need to be altered to allow an application to compile and run correctly on a
- * different board or microcontroller to the current configuration - if the options are incorrect, then the demo is most likely incompatible with the chosen
- * microcontroller model and cannot be made to function through the altering of the makefile settings alone (or at all). Settings such as the USB mode
- * (device, host or both), the USB interface speed and other LUFA configuration options can be set here - see \ref Page_TokenSummary documentation for details
- * on the available LUFA compile time configuration options.
+ * value specifies the path to the LUFA library core. This path may be relative or absolute, however note than even under Windows based systems the
+ * forward-slash (/) path seperator must be used.
+ *
+ * \section Sec_CC_FLAGS The CC_FLAGS Parameter
+ * This parameter lists the compiler flags passed to the C/C++ compiler, the assembler and the linker. These are used as-is directly to GCC and thus
+ * must match GCC's command line options as given in the GCC manual. This variable may be used to define tokens directly on the command line, enable or
+ * disable warnings, adjust the target-specific tuning parameters or other options.
+ *
+ * \section Sec_LD_FLAGS The LD_FLAGS Parameter
+ * This parameter lists the linker flags passed exclusively to the linker. These are used as-is directly to GCC and thus must match GCC's command line
+ * linker options as given in the GCC manual. This variable may be used to create or relocate custom data sections, or enable linker specific behaviors.
