  /**

   *  @defgroup io I/O

   *

   *  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  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++/manual/bk01pt11ch24.html
