// BOOST_[APPEND_]EXPLICIT_TEMPLATE_[NON_]TYPE macros --------------------------//
-//
-// Some compilers have problems with function templates whose template
-// parameters don't appear in the function parameter list (basically
-// they just link one instantiation of the template in the final
-// executable). These macros provide a uniform way to cope with the
-// problem with no effects on the calling syntax.
-
-// Example:
-//
-// #include <iostream>
-// #include <ostream>
-// #include <typeinfo>
-//
-// template <int n>
-// void f() { std::cout << n << ' '; }
-//
-// template <typename T>
-// void g() { std::cout << typeid(T).name() << ' '; }
-//
-// int main() {
-// f<1>();
-// f<2>();
-//
-// g<int>();
-// g<double>();
-// }
-//
-// With VC++ 6.0 the output is:
-//
-// 2 2 double double
-//
-// To fix it, write
-//
-// template <int n>
-// void f(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int, n)) { ... }
-//
-// template <typename T>
-// void g(BOOST_EXPLICIT_TEMPLATE_TYPE(T)) { ... }
-//
