28 *  This is a Standard C++ Library file.  You should @c \#include this file
29 *  in your programs, rather than any of the @a *.h implementation files.

31 *  This is the C++ version of the Standard C Library header @c stdio.h,
32 *  and its contents are (mostly) the same as that header, but are all
33 *  contained in the namespace @c std (except for names which are defined
34 *  as macros in C).
