Just FYI,  I believe you can do this

   #define LONG_STRING_CONST(...)  #__VA_ARGS__

   const std::stirng json = LONG_STRING_CONST(
      {
        "name": "gpu switch list",
        "version": "0.1",
        "entries": [
           ..etc...
        ]
     }
    );

Here and in other files. Might be easier in the future than having to escape
every quote and add a \n all over the place.

Wow, this is really awesome! Why I haven't heard of this before?  :)
