-# This script displays the field of rectangles used by --testset rtree

-#
-#      rm test.db
-#      ./speedtest1 --testset rtree --size 25 test.db
-#      sqlite3 --separator ' ' test.db 'SELECT * FROM rt1' >data.txt

-# The filename "data.txt" is hard coded into this script and so that name
-# must be used on lines 3 and 4 above.  Elsewhere, different filenames can
-# be used.  The --size N parameter can be adjusted as desired.
