-# Test organization:
-#
-# analyze2-1.*: Tests to verify that ANALYZE creates and populates the
-#               sqlite_stat2 table as expected.
-#
-# analyze2-2.*: Test that when a table has two indexes on it and either
-#               index may be used for the scan, the index suggested by
-#               the contents of sqlite_stat2 table is prefered.
-# 
-# analyze2-3.*: Similar to the previous block of tests, but using tables
-#               that contain a mixture of NULL, numeric, text and blob
-#               values.
-#
-# analyze2-4.*: Check that when an indexed column uses a collation other
-#               than BINARY, the collation is taken into account when
-#               using the contents of sqlite_stat2 to estimate the cost
-#               of a range scan.
-#
-# analyze2-5.*: Check that collation sequences are used as described above
-#               even when the only available version of the collation 
-#               function require UTF-16 encoded arguments.
-#
-# analyze2-6.*: Check that the library behaves correctly when one of the
-#               sqlite_stat2 or sqlite_stat1 tables are missing.
-#
-# analyze2-7.*: Check that in a shared-schema situation, nothing goes
-#               wrong if sqlite_stat2 data is read by one connection,
-#               and freed by another.
