// This file is a supermacro
// (see http://wanderinghorse.net/computing/papers/supermacros_cpp.html) to
// expand a definition 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).
// LATE_BINDING_SYMBOL_TABLE_DLL_NAME: String literal for the DLL file name to
//     load.
//
// From a .cc file, include the header file containing your call to the .h.def
// supermacro, and then call this supermacro (optionally from inside the
// namespace for the class to generate, if any). Example:
//
// #include "myclassname.h"
//
// namespace foo {
//
// #define LATE_BINDING_SYMBOL_TABLE_CLASS_NAME MY_CLASS_NAME
// #define LATE_BINDING_SYMBOL_TABLE_SYMBOLS_LIST MY_SYMBOLS_LIST
// #define LATE_BINDING_SYMBOL_TABLE_DLL_NAME "libdll.so.n"
// #include "talk/base/latebindingsymboltable.cc.def"
//
// }
