-* LGPLv2.1
-
-The library part is distributed under LGPLv2.1 or later. See lgpl-2.1.txt for
-details. This applies to :
-
-urcu.h
-urcu.c
-urcu-static.h
-arch_x86.h
-arch_ppc.h
-
-LGPL-compatible source code can statically use the library header using :
-
-#define _LGPL_SOURCE
-#include <urcu.h>
-
-Dynamic-only linking with the LGPL library is used if _LGPL_SOURCE is not
-defined. It permits relinking with newer versions of the library, which is
-required by the LGPL license.
-
-See lgpl-relicensing.txt for details.
