+// This is (yet another one) String class for C++ programmers. It doesn't use
+// any of "advanced" C++ features (i.e. templates, exceptions, namespaces...)
+// thus you should be able to compile it with practicaly any C++ compiler.
+// This class uses copy-on-write technique, i.e. identical strings share the
+// same memory as long as neither of them is changed.
+//
+// This class aims to be as compatible as possible with the new standard
+// std::string class, but adds some additional functions and should be at
+// least as efficient than the standard implementation.
+//
+// Performance note: it's more efficient to write functions which take "const
+// String&" arguments than "const char *" if you assign the argument to
+// another string.
+//
+// It was compiled and tested under Win32, Linux (libc 5 & 6), Solaris 5.5.
+//
+// To do:
+// - ressource support (string tables in ressources)
+// - more wide character (UNICODE) support
+// - regular expressions support
