/** \page Page_BuildSystem The LUFA Build System
 *
 *  \section Sec_BuildSystemOverview Overview of the LUFA Build System
 *  The LUFA build system is an attempt at making a set of re-usable, modular build make files which
 *  can be referenced in a LUFA powered project, to minimise the amount of code required in an
 *  application makefile. The system is written in GNU Make, and each module is independant of
 *  one-another.
 *
 *  To use a LUFA build system module, simply add an include to your project makefile:
 *  \code
 *  include $(LUFA_PATH)/Build/lufa.core.in
 *  \endcode
 *
 *  And the associated build module targets will be added to your project's build makefile automatically.
 *  To call a build target, run make {TARGET_NAME} from the command line, substituting in
 *  the appropriate target name.
 *
 *  \see \ref Sec_AppConfigParams for a copy of the sample LUFA project makefile.
 *
 *  Each build module may have one or more mandatory parameters (GNU Make variables) which must
 *  be supplied in the project makefile for the module to work, and one or more optional parameters which
 *  may be defined and which will assume a sensible default if not.
 *
 *  \section SSec_BuildSystemModules Available Modules
