\`configure' configures sqlite 3.17.0 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

  ** two forms, and only the specified schema is optimized in the latter two.
  **
  ** The details of optimizations performed by this pragma does are expected
  ** to change and improve over time.  Applications should anticipate that
  ** this pragma will perform new optimizations in future releases.
  **
  ** The optional argument is a bitmask of optimizations to perform:
  **
  **    0x0001    Debugging mode.  Do not actually perform any optimizations
  **              but instead return one line of text for each optimization
  **              that would have been done.  Off by default.
  **
  **    0x0002    Run ANALYZE on tables that might benefit.  On by default.
  **              See below for additional information.
  **
  **    0x0004    (Not yet implemented) Record usage and performance 
  **              information from the current session in the
  **              database file so that it will be available to "optimize"
  **              pragmas run by future database connections.
  **
  **    0x0008    (Not yet implemented) Create indexes that might have
  **              been helpful to recent queries
  **
  ** The default MASK is 0x000e, which means perform all of the optimizations
  ** listed above except do not set Debug Mode.  New optimizations may be
  ** added in future releases but they will be turned off by default.  The
  ** default MASK will always be 0x0e.
  **
  ** DETERMINATION OF WHEN TO RUN ANALYZE
  **
  ** In the current implementation, a table is analyzed if only if all of
  ** the following are true:
  **
  ** (1) MASK bit 0x02 is set.
  **
  ** (2) The query planner used sqlite_stat1-style statistics for one or
  **     more indexes of the table at some point during the lifetime of
  **     the current connection.
  **
  ** (3) One or more indexes of the table are currently unanalyzed OR
  **     the number of rows in the table has increased by 25 times or more
  **     since the last time ANALYZE was run.
  **
  ** The rules for when tables are analyzed are likely to change in
  ** future releases.

** names are not also used by explicitly declared columns. ^If

** ^The sqlite3_last_insert_rowid(D) interface usually returns the [rowid] of

** recorded. ^If no successful [INSERT]s into rowid tables have ever occurred 
** on the database connection D, then sqlite3_last_insert_rowid(D) returns 
** zero.
**
** As well as being set automatically as rows are inserted into database
** tables, the value returned by this function may be set explicitly by
** [sqlite3_set_last_insert_rowid()]
**
** Some virtual table implementations may INSERT rows into rowid tables as
** part of committing a transaction (e.g. to flush data accumulated in memory
** to disk). In this case subsequent calls to this function return the rowid
** associated with these internal INSERT operations, which leads to 
** unintuitive results. Virtual table implementations that do write to rowid
** tables in this way can avoid this problem by restoring the original 
** rowid value using [sqlite3_set_last_insert_rowid()] before returning 
** control to the user.
**
** ^(If an [INSERT] occurs within a trigger then this routine will 
** return the [rowid] of the inserted row as long as the trigger is 

** running. Once the trigger program ends, the value returned
