  15 ** This file is automatically generated by the script in the canonical
  16 ** SQLite source tree at tool/mkshellc.tcl.  That script combines source
  17 ** code from various constituent source files of SQLite into this single
  18 ** "shell.c" file used to implement the SQLite command-line shell.
  19 **
  20 ** Most of the code found below comes from the "src/shell.c.in" file in
  21 ** the canonical SQLite source tree.  That main file contains "INCLUDE"
  22 ** lines that specify other files in the canonical source tree that are
  23 ** inserted to getnerate this complete program source file.
  24 **
  25 ** The code from multiple files is combined into this single "shell.c"
  26 ** source file to help make the command-line program easier to compile.
  27 **
  28 ** To modify this program, get a copy of the canonical SQLite source tree,
  29 ** edit the src/shell.c.in" and/or some of the other files that are included
  30 ** by "src/shell.c.in", then rerun the tool/mkshellc.tcl script.
