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