** Most of the code found below comes from the "src/shell.c.in" file in

**

** The code from multiple files is combined into this single "shell.c"

** source file to help make the command-line program easier to compile.

**

** To modify this program, get a copy of the canonical SQLite source tree,

** edit the src/shell.c.in" and/or some of the other files that are included
