+ * This WinMain() function can be overridden by an application and
+ * is provided for compatibility with programs written for other
+ * operating systems that conform to the ANSI standard entry point
+ * "main()".  This will allow you to build a WIN32 Application
+ * without any special settings.
+ *
+ * Because of problems with the Microsoft Visual C++ header files
+ * and/or compiler, you cannot have a WinMain function in a DLL.
+ * I don't know why.  Thus, this nifty feature is only available
+ * if you link to the static library.
+ *
+ * Currently the debug version of this library will create a
+ * console window for your application so you can put printf()
+ * statements for debugging or informational purposes.  Ultimately
+ * we want to update this to always use the parent's console,
+ * but at present we have not identified a function or API in
+ * Microsoft(r) Windows(r) that allows for it.
