      Usage instructions for applications calling the sqlite3 API functions:

        In your application, call sqlite3_enable_load_extension(db,1) to
        allow loading external libraries.  Then load the library libsqlitefunctions
        using sqlite3_load_extension; the third argument should be 0.
        See http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
        Select statements may now use these functions, as in
        SELECT cos(radians(inclination)) FROM satsum WHERE satnum = 25544;

      Usage instructions for the sqlite3 program:

        If the program is built so that loading extensions is permitted,
        the following will work:
         sqlite> SELECT load_extension('#{lib}/libsqlitefunctions.dylib');
         sqlite> select cos(radians(45));
         0.707106781186548
