+// SigslotTester(s) are utility classes to check if signals owned by an
+// object are being invoked at the right time and with the right arguments.
+// They are meant to be used in tests. Tests must provide "capture" pointers
+// (i.e. address of variables) where the arguments from the signal callback
+// can be stored.
+//
+// Example:
+//   /* Some signal */
+//   sigslot::signal1<const std::string&> foo;
+//
+//   /* We want to monitor foo in some test. Note how signal argument is
+//      const std::string&, but capture-type is std::string. Capture type
+//      must be type that can be assigned to. */
+//   std::string capture;
+//   SigslotTester1<const std::string&, std::string> slot(&foo, &capture);
+//   foo.emit("hello");
+//   EXPECT_EQ(1, slot.callback_count());
+//   EXPECT_EQ("hello", capture);
+//   /* See unit-tests for more examples */
