/** \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.
*
* For details on the prerequisites needed for Linux and Windows machines to be able to use the LUFA
* build system, see \ref Sec_Prerequisites.
*
* To use a LUFA build system module, simply add an include to your project makefile:
* \code
* include $(LUFA_PATH)/Build/lufa_core.mk
* \endcode
*
* And the associated build module targets will be added to your project's build makefile automatically.
* To call a build target, run <tt>make {TARGET_NAME}</tt> 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 <i>must</i>
* 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
*
* The following modules are included in this LUFA release:
*
* \li \subpage Page_BuildModule_ATPROGRAM - Device Programming

/** \page Page_BuildModule_BUILD The BUILD build module
*
* The BUILD LUFA build system module, providing targets for the compilation,
* assembling and linking of an application from source code into binary files
* suitable for programming into a target device.
*
* To use this module in your application makefile, add the following code:
* \code

/** \page Page_BuildModule_SOURCES The SOURCES build module
*
* The SOURCES LUFA build system module, providing variables listing the various LUFA source files
* required to be build by a project for a given LUFA module. This module gives a way to reference
* LUFA source files symbollically, so that changes to the library structure do not break the library
* makefile.
*
* To use this module in your application makefile, add the following code:
* \code
* include $(LUFA_PATH)/Build/lufa_sources.mk
* \endcode
*
* \section SSec_BuildModule_SOURCES_Requirements Requirements
* None.
