-/** \page Page_BuildLibrary Building as a Linkable Library
- *
- *  The LUFA library can be built as a proper linkable library (with the extension .a) under AVR-GCC, so that
- *  the library does not need to be recompiled with each revision of a user project. Instructions for creating
- *  a library from a given source tree can be found in the AVR-GCC user manual included in the WinAVR install
- *  /Docs/ directory.
- *
- *  However, building the library is <b>not recommended</b>, as the static (compile-time) options will be
- *  unable to be changed without a recompilation of the LUFA code. Therefore, if the library is to be built
- *  from the LUFA source, it should be made to be application-specific and compiled with the static options
- *  that are required for each project (which should be recorded along with the library).
- *
- *  Normal library use has the library components compiled in at the same point as the application code, as
- *  demonstrated in the library demos and applications. This is the preferred method, as the library is recompiled
- *  each time to ensure that all static options for a particular application are applied.
