+// The MATCHER* family of macros can be used in a namespace scope to
+// define custom matchers easily.  The syntax:
+//
+//   MATCHER(name, description_string) { statements; }
+//
+// will define a matcher with the given name that executes the
+// statements, which must return a bool to indicate if the match
+// succeeds.  Inside the statements, you can refer to the value being
+// matched by 'arg', and refer to its type by 'arg_type'.
+//
+// The description string documents what the matcher does, and is used
+// to generate the failure message when the match fails.  Since a
+// MATCHER() is usually defined in a header file shared by multiple
+// C++ source files, we require the description to be a C-string
+// literal to avoid possible side effects.  It can be empty, in which
+// case we'll use the sequence of words in the matcher name as the
+// description.
+//
+// For example:
+//
+//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
+//
+// allows you to write
+//
+//   // Expects mock_foo.Bar(n) to be called where n is even.
+//   EXPECT_CALL(mock_foo, Bar(IsEven()));
+//
+// or,
+//
+//   // Verifies that the value of some_expression is even.
+//   EXPECT_THAT(some_expression, IsEven());
+//
+// If the above assertion fails, it will print something like:
+//
+//   Value of: some_expression
+//   Expected: is even
+//     Actual: 7
+//
+// where the description "is even" is automatically calculated from the
+// matcher name IsEven.
+//
+// Note that the type of the value being matched (arg_type) is
+// determined by the context in which you use the matcher and is
+// supplied to you by the compiler, so you don't need to worry about
+// declaring it (nor can you).  This allows the matcher to be
+// polymorphic.  For example, IsEven() can be used to match any type
+// where the value of "(arg % 2) == 0" can be implicitly converted to
+// a bool.  In the "Bar(IsEven())" example above, if method Bar()
+// takes an int, 'arg_type' will be int; if it takes an unsigned long,
+// 'arg_type' will be unsigned long; and so on.
+//
+// Sometimes you'll want to parameterize the matcher.  For that you
+// can use another macro:
+//
+//   MATCHER_P(name, param_name, description_string) { statements; }
+//
+// For example:
+//
+//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
+//
+// will allow you to write:
+//
+//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
+//
+// which may lead to this message (assuming n is 10):
+//
+//   Value of: Blah("a")
+//   Expected: has absolute value 10
+//     Actual: -9
+//
+// Note that both the matcher description and its parameter are
+// printed, making the message human-friendly.
+//
+// In the matcher definition body, you can write 'foo_type' to
+// reference the type of a parameter named 'foo'.  For example, in the
+// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
+// 'value_type' to refer to the type of 'value'.
+//
+// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
+// support multi-parameter matchers.
+//
+// When defining a parameterized matcher, you can use Python-style
+// interpolations in the description string to refer to the parameter
+// values.  We support the following syntax currently:
+//
+//   %%       a single '%' character
+//   %(*)s    all parameters of the matcher printed as a tuple
+//   %(foo)s  value of the matcher parameter named 'foo'
+//
+// For example,
+//
+//   MATCHER_P2(InClosedRange, low, hi, "is in range [%(low)s, %(hi)s]") {
+//     return low <= arg && arg <= hi;
+//   }
+//   ...
+//   EXPECT_THAT(3, InClosedRange(4, 6));
+//
+// would generate a failure that contains the message:
+//
+//   Expected: is in range [4, 6]
+//
+// If you specify "" as the description, the failure message will
+// contain the sequence of words in the matcher name followed by the
+// parameter values printed as a tuple.  For example,
+//
+//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
+//   ...
+//   EXPECT_THAT(3, InClosedRange(4, 6));
+//
+// would generate a failure that contains the text:
+//
+//   Expected: in closed range (4, 6)
+//
+// For the purpose of typing, you can view
+//
+//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
+//
+// as shorthand for
+//
+//   template <typename p1_type, ..., typename pk_type>
+//   FooMatcherPk<p1_type, ..., pk_type>
+//   Foo(p1_type p1, ..., pk_type pk) { ... }
+//
+// When you write Foo(v1, ..., vk), the compiler infers the types of
+// the parameters v1, ..., and vk for you.  If you are not happy with
+// the result of the type inference, you can specify the types by
+// explicitly instantiating the template, as in Foo<long, bool>(5,
+// false).  As said earlier, you don't get to (or need to) specify
+// 'arg_type' as that's determined by the context in which the matcher
+// is used.  You can assign the result of expression Foo(p1, ..., pk)
+// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
+// can be useful when composing matchers.
+//
+// While you can instantiate a matcher template with reference types,
+// passing the parameters by pointer usually makes your code more
+// readable.  If, however, you still want to pass a parameter by
+// reference, be aware that in the failure message generated by the
+// matcher you will see the value of the referenced object but not its
+// address.
+//
+// You can overload matchers with different numbers of parameters:
+//
+//   MATCHER_P(Blah, a, description_string1) { ... }
+//   MATCHER_P2(Blah, a, b, description_string2) { ... }
+//
+// While it's tempting to always use the MATCHER* macros when defining
+// a new matcher, you should also consider implementing
+// MatcherInterface or using MakePolymorphicMatcher() instead,
+// especially if you need to use the matcher a lot.  While these
+// approaches require more work, they give you more control on the
+// types of the value being matched and the matcher parameters, which
+// in general leads to better compiler error messages that pay off in
+// the long run.  They also allow overloading matchers based on
+// parameter types (as opposed to just based on the number of
+// parameters).
+//
+// CAVEAT:
+//
+// MATCHER*() can only be used in a namespace scope.  The reason is
+// that C++ doesn't yet allow function-local types to be used to
+// instantiate templates.  The up-coming C++0x standard will fix this.
+// Once that's done, we'll consider supporting using MATCHER*() inside
+// a function.
+//
+// MORE INFORMATION:
+//
+// To learn more about using these macros, please search for 'MATCHER'
+// on http://code.google.com/p/googlemock/wiki/CookBook.
