-// Differences from `StringPrintf()`:
-//   * The format std::string does not identify the types of arguments. Instead, the
-//     arguments are implicitly converted to strings. See below for a list of
-//     accepted types.
-//   * Substitutions in the format std::string are identified by a '$' followed by a
-//     single digit. You can use arguments out-of-order and use the same
-//     argument multiple times.
-//   * A '$$' sequence in the format std::string means output a literal '$'
-//     character.
-//   * `Substitute()` is significantly faster than `StringPrintf()`. For very
-//     large strings, it may be orders of magnitude faster.
 //
 // Supported types:
 //   * absl::string_view, std::string, const char* (null is equivalent to "")
