+/* This header makes available replacements working in both C and C++ for the
+   obsolete osl/diagnose.h functionality that in turn is used from both C and
+   C++ code and the obsolete tools/debug.hxx functionality that uses printf-style
+   formatting.  Once that obsolete functionality is removed, this header can be
+   removed, too.
+
+   This header uses variadic macros in both C (where they are officially only
+   supported since C99) and C++ (where they are officially only supported since
+   C++11).  It appears that all relevant compilers (esp. GCC 4.0 and MS VS 2008
+   Express) already support them in their C and C++ dialects.  See also
+   <http://wiki.apache.org/stdcxx/C++0xCompilerSupport>.
+
+   Avoid the use of other sal code in this header as much as possible, so that
+   this code can be called from other sal code without causing endless
+   recursion.
