# Test plan:
#
#   rtree-1.*: Creating/destroying r-tree tables.
#   rtree-2.*: Test the implicit constraints - unique rowid and
#              (coord[N]<=coord[N+1]) for even values of N. Also
#              automatic assigning of rowid values.
#   rtree-3.*: Linear scans of r-tree data.
#   rtree-4.*: Test INSERT
#   rtree-5.*: Test DELETE
#   rtree-6.*: Test UPDATE
#   rtree-7.*: Test renaming an r-tree table.
#   rtree-8.*: Test constrained scans of r-tree data.
