-** This file is automatically generated by the script in the canonical

-** 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.

-** occurs before the start of each row.  N means a NULL value.
-** I mean an 8-byte little-endian integer <int>.  F is a floating point
-** number with an 8-byte little-endian IEEE floating point value <ieee-float>.
-** B means blobs of <size> bytes.  T means text rendered as <size>
-** bytes of UTF-8.  The <n> and <size> values are expressed as an ASCII
-** text integers.
-**
-** For each SQL statement in the X input, there is one S segment.  Each
-** S segment is followed by zero or more R segments, one for each row in the
-** result set.  After each R, there are one or more N, I, F, B, or T segments,

-** This file implements an eponymous virtual table that returns suggested
-** completions for a partial SQL input.
-**
-** Suggested usage:
-**
-**     SELECT DISTINCT candidate COLLATE nocase
-**       FROM completion($prefix,$wholeline)
-**      ORDER BY 1;
-**
-** The two query parameters are optional.  $prefix is the text of the
-** current word being typed and that is to be completed.  $wholeline is
-** the complete input line, used for context.
-**
-** The raw completion() table might return the same candidate multiple
-** times, for example if the same column name is used to two or more
-** tables.  And the candidates are returned in an arbitrary order.  Hence,
-** the DISTINCT and ORDER BY are recommended.
-**
-** This virtual table operates at the speed of human typing, and so there
-** is no attempt to make it fast.  Even a slow implementation will be much
-** faster than any human can type.
