/**
* @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<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++/manual/bk01pt11ch24.html
