**
******************************************************************************
**
** This file implements a utility function (and a utility program) that
** makes a copy of an SQLite database while simultaneously zeroing out all
** deleted content.
**
** Normally (when PRAGMA secure_delete=OFF, which is the default) when SQLite
** deletes content, it does not overwrite the deleted content but rather marks
** the region of the file that held that content as being reusable. This can
** cause deleted content to recoverable from the database file. This stale
** content is removed by the VACUUM command, but VACUUM can be expensive for
** large databases. When in PRAGMA secure_delete=ON mode, the deleted content
** is zeroed, but secure_delete=ON has overhead as well.
**
** This utility attempts to make a copy of a complete SQLite database where
** all of the deleted content is zeroed out in the copy, and it attempts to
** do so while being faster than running VACUUM.
**
** Usage:
**
** int sqlite3_scrub_backup(
** const char *zSourceFile, // Source database filename
** const char *zDestFile, // Destination database filename
** char **pzErrMsg // Write error message here
** );
**
** Simply call the API above specifying the filename of the source database
** and the name of the backup copy. The source database must already exist
** and can be in active use. (A read lock is held during the backup.) The
** destination file should not previously exist. If the pzErrMsg parameter
** is non-NULL and if an error occurs, then an error message might be written
** into memory obtained from sqlite3_malloc() and *pzErrMsg made to point to
** that error message. But if the error is an OOM, the error might not be
** reported. The routine always returns non-zero if there is an error.
**
** If compiled with -DSCRUB_STANDALONE then a main() procedure is added and
** this file becomes a standalone program that can be run as follows:
**
** ./sqlite3scrub SOURCE DEST
