** 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.
