 ** This file is an amalgamation of many separate C source files from SQLite
 ** version $VERSION.  By combining all the individual C code files into this 
 ** single large file, the entire code can be compiled as a single translation
 ** unit.  This allows many compilers to do optimizations that would not be
 ** possible if the files were compiled separately.  Performance improvements
 ** of 5% or more are commonly seen when SQLite is compiled as a single
 ** translation unit.
