+******************************************************************************
+**
+** This file implements a stand-alone utility program that converts
+** a binary file (usually an SQLite database) into a text format that
+** is compact and friendly to human-readers.
+**
+** Usage:
+**
+**         dbtotxt [--pagesize N] FILENAME
+**
+** The translation of the database appears on standard output.  If the
+** --pagesize command-line option is omitted, then the page size is taken
+** from the database header.
+**
+** Compactness is achieved by suppressing lines of all zero bytes.  This
+** works well at compressing test databases that are mostly empty.  But
+** the output will probably be lengthy for a real database containing lots
+** of real content.  For maximum compactness, it is suggested that test
+** databases be constructed with "zeroblob()" rather than "randomblob()"
+** used for filler content and with "PRAGMA secure_delete=ON" selected to
+** zero-out deleted content.
