-# Test cases autovacuum-1.* work as follows:
-#
-# 1. A table with a single indexed field is created.
-# 2. Approximately 20 rows are inserted into the table. Each row is long 
-#    enough such that it uses at least 2 overflow pages for both the table 
-#    and index entry.
-# 3. The rows are deleted in a psuedo-random order. Sometimes only one row
-#    is deleted per transaction, sometimes more than one.
-# 4. After each transaction the table data is checked to ensure it is correct
-#    and a "PRAGMA integrity_check" is executed.
-# 5. Once all the rows are deleted the file is checked to make sure it 
-#    consists of exactly 4 pages.
-#
-# Steps 2-5 are repeated for a few different psuedo-random delete patterns 
-# (defined by the $delete_orders list).

-# Tests cases autovacuum-2.* test that root pages are allocated

-#
-# autovacuum-2.1.*: Drop the tables that currently exist in the database.
-# autovacuum-2.2.*: Create some tables. Ensure that data pages can be
-#                   moved correctly to make space for new root-pages.
-# autovacuum-2.3.*: Drop one of the tables just created (not the last one),
-#                   and check that one of the other tables is moved to
-#                   the free root-page location.
-# autovacuum-2.4.*: Check that a table can be created correctly when the
-#                   root-page it requires is on the free-list.
-# autovacuum-2.5.*: Check that a table with indices can be dropped. This
-#                   is slightly tricky because dropping one of the
-#                   indices/table btrees could move the root-page of another.
-#                   The code-generation layer of SQLite overcomes this problem
-#                   by dropping the btrees in descending order of root-pages.
-#                   This test ensures that this actually happens.
