+ * This is a stub implementation of main that can be used to include an *.ino
+ * file which is so close to C++ that many of them can be compiled as C++. The
+ * notable difference between a *.ino file and a *.cpp file is that the *.ino
+ * file does not need to include function prototypes, and are instead
+ * auto-generated.
