-// For historic reasons, we don't use std::string.

-// TODO(wan@google.com): replace this class with std::string or
-// implement it in terms of the latter.
-//
-// Note that String can represent both NULL and the empty string,
-// while std::string cannot represent NULL.
-//
-// NULL and the empty string are considered different. NULL is less
-// than anything (including the empty string) except itself.
-//
-// This class only provides minimum functionality necessary for
-// implementing Google Test. We do not intend to implement a full-fledged
-// string class here.
-//
-// Since the purpose of this class is to provide a substitute for
-// std::string on platforms where it cannot be used, we define a copy
-// constructor and assignment operators such that we don't need
-// conditional compilation in a lot of places.
-//
-// In order to make the representation efficient, the d'tor of String
-// is not virtual. Therefore DO NOT INHERIT FROM String.
+// String - an abstract class holding static string utilities.
