* @name Standard Stream Objects

* http://gcc.gnu.org/onlinedocs/libstdc++/manual/bk01pt11ch24.html
* and the @link iosfwd I/O forward declarations @endlink
*
* They are required by default to cooperate with the global C

* startup and termination. For more information, see the HOWTO
* linked to above.
