+// This file is a supermacro
+// (see http://wanderinghorse.net/computing/papers/supermacros_cpp.html) to
+// expand a declaration of a late-binding symbol table class.
+//
+// Arguments:
+// LATE_BINDING_SYMBOL_TABLE_CLASS_NAME: Name of the class to generate.
+// LATE_BINDING_SYMBOL_TABLE_SYMBOLS_LIST: List of symbols to load from the DLL,
+//     as an X-Macro list (see http://www.drdobbs.com/blogs/cpp/228700289).
+//
+// From a .h file, include the header(s) for the DLL to late-bind and the
+// latebindingsymboltable.h header, and then call this supermacro (optionally
+// from inside the namespace for the class to generate, if any). Example:
+//
+// #include <headerfordll.h>
+//
+// #include "webrtc/base/latebindingsymboltable.h"
+//
+// namespace foo {
+//
+// #define MY_CLASS_NAME DesiredClassName
+// #define MY_SYMBOLS_LIST X(acos) X(sin) X(tan)
+//
+// #define LATE_BINDING_SYMBOL_TABLE_CLASS_NAME MY_CLASS_NAME
+// #define LATE_BINDING_SYMBOL_TABLE_SYMBOLS_LIST MY_SYMBOLS_LIST
+// #include "webrtc/base/latebindingsymboltable.h.def"
+//
+// }
