- * @defgroup s27_2_iosfwd I/O Forward Declarations
- *
- * Nearly all of the I/O classes are parameterized on the type of
- * characters they read and write. (The major exception is ios_base at
- * the top of the hierarchy.) This is a change from pre-Standard
- * streams, which were not templates.
- *
- * For ease of use and compatibility, all of the basic_* I/O-related
- * classes are given typedef names for both of the builtin character
- * widths (wide and narrow). The typedefs are the same as the
- * pre-Standard names, for example:
- *
- * @code
- * typedef basic_ifstream<char> ifstream;
- * @endcode
- *
- * Because properly forward-declaring these classes can be difficult, you
- * should not do it yourself. Instead, include the <iosfwd>
- * header, which contains only declarations of all the I/O classes as
- * well as the typedefs. Trying to forward-declare the typedefs
- * themselves (e.g., "class ostream;") is not valid ISO C++.
- *
- * For more specific declarations, see
- * http://gcc.gnu.org/onlinedocs/libstdc++/27_io/howto.html#10
