# This script displays the field of rectangles used by --testset rtree
# of speedtest1. Run this script as follows:
#
# rm test.db
# ./speedtest1 --testset rtree --size 25 test.db
# sqlite3 --separator ' ' test.db 'SELECT * FROM rt1' >data.txt
# wish show_speedtest1_rtree.tcl
#
# 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.
