  // This collection contains one entry for each op. If an op is added it must be
  // added to this list.
  //
  // In order to use this list you want to define a macro named exactly NGRAPH_OP
  // When you are done you should undef the macro
  // As an example if you wanted to make a list of all op names as strings you could do this:
  //
  // #define NGRAPH_OP(a,b) #a,
  // std::vector<std::string> op_names{
  // #include "this include file name"
  // };
  // #undef NGRAPH_OP
  //
  // This sample expands to a list like this:
  // "Abs",
  // "Acos",
  // ...
  //
  // #define NGRAPH_OP(a,b) b::a,
  // std::vector<std::string> op_names{
  // #include "this include file name"
  // };
  // #undef NGRAPH_OP
  //
  // This sample expands to a list like this:
  // ngraph::op::Abs,
  // ngraph::op::Acos,
  // ...
  //
  // It's that easy. You can use this for fun and profit.
