+// Sometimes you want to give an action explicit template parameters
+// that cannot be inferred from its value parameters. ACTION() and
+// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
+// and can be viewed as an extension to ACTION() and ACTION_P*().
+//
+// The syntax:
+//
+// ACTION_TEMPLATE(ActionName,
+// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
+// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
+//
+// defines an action template that takes m explicit template
+// parameters and n value parameters. name_i is the name of the i-th
+// template parameter, and kind_i specifies whether it's a typename,
+// an integral constant, or a template. p_i is the name of the i-th
+// value parameter.
+//
+// Example:
+//
+// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
+// // function to type T and copies it to *output.
+// ACTION_TEMPLATE(DuplicateArg,
+// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
+// AND_1_VALUE_PARAMS(output)) {
+// *output = T(::std::get<k>(args));
+// }
+// ...
+// int n;
+// EXPECT_CALL(mock, Foo(_, _))
+// .WillOnce(DuplicateArg<1, unsigned char>(&n));
+//
+// To create an instance of an action template, write:
+//
+// ActionName<t1, ..., t_m>(v1, ..., v_n)
+//
+// where the ts are the template arguments and the vs are the value
+// arguments. The value argument types are inferred by the compiler.
+// If you want to explicitly specify the value argument types, you can
+// provide additional template arguments:
+//
+// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
+//
+// where u_i is the desired type of v_i.
+//
+// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
+// number of value parameters, but not on the number of template
+// parameters. Without the restriction, the meaning of the following
+// is unclear:
+//
+// OverloadedAction<int, bool>(x);
+//
+// Are we using a single-template-parameter action where 'bool' refers
+// to the type of x, or are we using a two-template-parameter action
+// where the compiler is asked to infer the type of x?
+//
+// Implementation notes:
+//
+// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
+// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
+// implementing ACTION_TEMPLATE. The main trick we use is to create
+// new macro invocations when expanding a macro. For example, we have
+//
+// #define ACTION_TEMPLATE(name, template_params, value_params)
+// ... GMOCK_INTERNAL_DECL_##template_params ...
+//
+// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
+// to expand to
+//
+// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
+//
+// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
+// preprocessor will continue to expand it to
+//
+// ... typename T ...
+//
+// This technique conforms to the C++ standard and is portable. It
+// allows us to implement action templates using O(N) code, where N is
+// the maximum number of template/value parameters supported. Without
+// using it, we'd have to devote O(N^2) amount of code to implement all
+// combinations of m and n.
+
+// Declares the template parameters.
