+/// How C and C++ code looks to the tokenizer. C++ knows all the words of C, so both share one set of
+/// rules.
+/// </summary>
+/// <remarks>
+/// A directive of the preprocessor, such as #include, runs to the end of its line. A raw string of C++,
+/// such as R"(…)", reads like any other string, which differs only when it holds a quotation mark.
