+** This file is automatically generated by the script in the canonical
+** SQLite source tree at tool/mkshellc.tcl.  That script combines source
+** code from various constituent source files of SQLite into this single
+** "shell.c" file used to implement the SQLite command-line shell.
+**
+** Most of the code found below comes from the "src/shell.c.in" file in
+** the canonical SQLite source tree.  That main file contains "INCLUDE"
+** lines that specify other files in the canonical source tree that are
+** inserted to getnerate this complete program source file.
+**
+** 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
+** by "src/shell.c.in", then rerun the tool/mkshellc.tcl script.
