# Test cases are organized roughly as follows:
#
# collate4-1.* ORDER BY.
# collate4-2.* WHERE clauses.
# collate4-3.* constraints (primary key, unique).
# collate4-4.* simple min() or max() queries.
# collate4-5.* REINDEX command
# collate4-6.* INTEGER PRIMARY KEY indices.
#
#
# These tests - collate4-1.* - check that indices are correctly
# selected or not selected to implement ORDER BY clauses when
# user defined collation sequences are involved.
#
# Because these tests also exercise all the different ways indices
# can be created, they also serve to verify that indices are correctly
# initialised with user-defined collation sequences when they are
# created.
#
# Tests named collate4-1.1.* use indices with a single column. Tests
# collate4-1.2.* use indices with two columns.
