-//
-// 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.

-//  - ressource support (string tables in ressources)
-//  - more wide character (UNICODE) support
-//  - regular expressions support
