# We'll test 2-way, 3-way, and 4-way joins and figure that if those work,
# everything else does as well.  We'll create test databases called
# sub1.db, sub2.db, sub3.db, and sub4.db.  The number on the database
# describes the duplication -- duplicates are of the form 0, N, 2N, 3N, ...
# where N is the number of the database.  Primary.db is the primary database,
# and sub0.db is the database that has no matching duplicates.  All of
# these are within a single database.
#
# We should test this on all btrees, all hash, and a combination thereof
