-/** \page Page_BuildSystem The LUFA Build System
- *
- * \section Sec_BuildSystem_Overview Overview of the LUFA Build System
- * The LUFA build system was originally an attempt at making a set of
- * re-usable, modular build make files which could be referenced in a LUFA
- * powered project, to minimize the amount of code required in an
- * application makefile.
- *
- * As it turned out to be fairly generic in nature, it was split out into its
- * own separate project, called DMBS (<i>Dean's Makefile Build System</i>)
- * which is released into the public domain. LUFA-specific portions of the
- * LUFA build system extend DMBS, and provide a universal build system for all
- * LUFA projects.
- *
- * The latest DMBS project information and documentation can be found at:
- * https://github.com/abcminiuser/dmbs
- *
- * DMBS is written in GNU Make, and each module is independent of one-another.
- *
- * LUFA now uses DMBS for its build system, with some LUFA specific extension
- * modules.
- *
- * If you have problems building using LUFA, see \subpage Page_BuildTroubleshooting for resolution steps.

-/** \page Page_BuildModule_LUFA_SOURCES LUFA SOURCES extension module for DMBS
- *
- * The LUFA SOURCES extension more for DMBS provides LUFA specific 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
- * symbolically, so that changes to the library structure do not break the
- * library makefile.

-/** \page Page_BuildTroubleshooting Troubleshooting Information
- *
- * LUFA uses a lot of advanced features of the AVR-GCC compiler, linker, and
- * surrounding binaries. This can sometimes lead to problems compiling
- * applications if one of these features is buggy in the version of the tools
- * used in a build environment. Missing utilities and incorrectly set makefile
- * configuration options can also result in different errors being produced
- * when compilation or other operations are attempted. The table below lists a
- * set of commonly encountered errors and their resolutions.
- *
- * <table>

- * <tr>
- * <td>Error "<b><tt>makefile:{X}: {Y}.mk: No such file or directory</tt></b>" shown when make is invoked.</td>
