  /** This file contains classes for wrapping an std::istream or
      std::ostream around a Mangle::Stream.

      This allows you to use Mangle streams in places that require std
      streams.

      This is much easier than trying to make your own custom streams
      into iostreams. The std::iostream interface is horrible and NOT
      designed for easy subclassing. Create a Mangle::Stream instead,
      and use this wrapper.
