+// This is a useless library. To use such a useless thing, with the EnableInterrupt library,
+// you need to #define LIBCALL_ENABLEINTERRUPT in your library, like so:
+#define LIBCALL_ENABLEINTERRUPT
+// Thus, none of the functions or ISRs will get compiled but their prototypes are declared
+// so you can use them as illustrated in the Useless.cpp.
+
+// You also need to #include the EnableInterrupt.h file in your sketch. After you #include the
+// EnableInterrupt.h file, #include the library's .h file (ie, this one in this example). This
+// will compile the requisite components. See the SimpleWithLibrary.ino sketch.
