-** The "printf" code that follows dates from the 1980's.  It is in
-** the public domain.  The original comments are included here for
-** completeness.  They are very out-of-date but might be useful as
-** an historical reference.  Most of the "enhancements" have been backed
-** out so that the functionality is now the same as standard printf().
-**
-**************************************************************************
-**
-** This file contains code for a set of "printf"-like routines.  These
-** routines format strings much like the printf() from the standard C
-** library, though the implementation here has enhancements to support
-** SQLlite.
