+}
+puts "    The number of $pageSize-byte pages that go into forming the complete
+    database"
+puts {
+Pages that store data
+
+    The number of pages that store data, either as primary B*Tree pages or
+    as overflow pages.  The number at the right is the data pages divided by
+    the total number of pages in the file.
+
+Pages on the freelist
+
+    The number of pages that are not currently in use but are reserved for
+    future use.  The percentage at the right is the number of freelist pages
+    divided by the total number of pages in the file.
+
+Pages of auto-vacuum overhead
+
+    The number of pages that store data used by the database to facilitate
+    auto-vacuum. This is zero for databases that do not support auto-vacuum.
+
+Number of tables in the database
+
+    The number of tables in the database, including the SQLITE_SCHEMA table
+    used to store schema information.
+
+Number of indices
+
+    The total number of indices in the database.
+
+Number of defined indices
+
+    The number of indices created using an explicit CREATE INDEX statement.
+
+Number of implied indices
+
+    The number of indices used to implement PRIMARY KEY or UNIQUE constraints
+    on tables.
+
+Size of the file in bytes
+
+    The total amount of disk space used by the entire database files.
+
+Bytes of user payload stored
+
+    The total number of bytes of user payload stored in the database. The
+    schema information in the SQLITE_SCHEMA table is not counted when
+    computing this number.  The percentage at the right shows the payload
+    divided by the total file size.
+
+Percentage of total database
+
+    The amount of the complete database file that is devoted to storing
+    information described by this category.
+
+Number of entries
+
+    The total number of B-Tree key/value pairs stored under this category.
+
+Bytes of storage consumed
+
+    The total amount of disk space required to store all B-Tree entries
+    under this category.  The is the total number of pages used times
+    the pages size.
+
+Bytes of payload
+
+    The amount of payload stored under this category.  Payload is the data
+    part of table entries and the key part of index entries.  The percentage
+    at the right is the bytes of payload divided by the bytes of storage 
+    consumed.
+
+Bytes of metadata
+
+    The amount of formatting and structural information stored in the
+    table or index.  Metadata includes the btree page header, the cell pointer
+    array, the size field for each cell, the left child pointer or non-leaf
+    cells, the overflow pointers for overflow cells, and the rowid value for
+    rowid table cells.  In other words, metadata is everything that is neither
+    unused space nor content.  The record header in the payload is counted as
+    content, not metadata.
+
+Average payload per entry
+
+    The average amount of payload on each entry.  This is just the bytes of
+    payload divided by the number of entries.
+
+Average unused bytes per entry
+
+    The average amount of free space remaining on all pages under this
+    category on a per-entry basis.  This is the number of unused bytes on
+    all pages divided by the number of entries.
+
+Non-sequential pages
+
+    The number of pages in the table or index that are out of sequence.
+    Many filesystems are optimized for sequential file access so a small
+    number of non-sequential pages might result in faster queries,
+    especially for larger database files that do not fit in the disk cache.
+    Note that after running VACUUM, the root page of each table or index is
+    at the beginning of the database file and all other pages are in a
+    separate part of the database file, resulting in a single non-
+    sequential page.
+
+Maximum payload per entry
+
+    The largest payload size of any entry.
+
+Entries that use overflow
+
+    The number of entries that user one or more overflow pages.
+
+Total pages used
+
+    This is the number of pages used to hold all information in the current
+    category.  This is the sum of index, primary, and overflow pages.
+
+Index pages used
+
+    This is the number of pages in a table B-tree that hold only key (rowid)
+    information and no data.
+
+Primary pages used
+
+    This is the number of B-tree pages that hold both key and data.
+
+Overflow pages used
+
+    The total number of overflow pages used for this category.
+
+Unused bytes on index pages
+
+    The total number of bytes of unused space on all index pages.  The
+    percentage at the right is the number of unused bytes divided by the
+    total number of bytes on index pages.
+
+Unused bytes on primary pages
+
+    The total number of bytes of unused space on all primary pages.  The
+    percentage at the right is the number of unused bytes divided by the
+    total number of bytes on primary pages.
+
+Unused bytes on overflow pages
+
+    The total number of bytes of unused space on all overflow pages.  The
+    percentage at the right is the number of unused bytes divided by the
+    total number of bytes on overflow pages.
+
+Unused bytes on all pages
+
+    The total number of bytes of unused space on all primary and overflow 
+    pages.  The percentage at the right is the number of unused bytes 
+    divided by the total number of bytes.
