//*****************************************************************************
//
// SYNOPSIS
//
	file_info::file_info(
		char const *file_name, size_t size, char const *title
	)
//
// DESCRIPTION
//
//	Construct a file_info.  This is out-of-line since it's doubtful that
//	a compiler will inline the initialization of all the data members.
//
//*****************************************************************************

//*****************************************************************************
//
// SYNOPSIS
//
	void* file_info::operator new( size_t size )
//
// DESCRIPTION
//
//	Allocate the memory as usual for an instance of file_info, but also
//	record its address so the entire collection can be iterated over
//	later.  Also, the first time through, reserve Files_Default slots for
//	files.  If exceeded, the vector will automatically grow, however.
//
// PARAMETERS
//
//	size	The size of the object to be allocated passed to us by the
//		implementation.
//
// RETURN VALUE
//
//	The pointer to the raw memory for the object to be constructed in.
//
//*****************************************************************************

//*****************************************************************************
//
// SYNOPSIS
//
	std::ostream& operator<<( std::ostream &o, file_info const &f )
//
// DESCRIPTION
//
//	Write the representation for a file_info to the given stream.
//
// PARAMETERS
//
//	o	The ostream to write to.
//
// RETURN VALUE
//
//	Returns the given ostream as is standard practice.
