+# 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.
