+# alter-1.9.*: Tests for ALTER TABLE when their is whitespace between the
+#     table name and left parenthesis token. i.e: 
+#     "CREATE TABLE abc       (a, b, c);"
+# alter-2.*: Test error conditions and messages.
+# alter-3.*: Test ALTER TABLE on tables that have TRIGGERs attached to them.
+# alter-4.*: Test ALTER TABLE on tables that have AUTOINCREMENT fields.
+# ...
+# alter-12.*: Test ALTER TABLE on views.

+# autovacuum-2.2.*: Create some tables. Ensure that data pages can be
+#                   moved correctly to make space for new root-pages.

+# autovacuum-2.5.*: Check that a table with indices can be dropped. This

+# The following procedure runs with SQLite's IO error simulation 
+# enabled.
+#
+#   1) Start with a reasonably sized database. One that includes the
+#      pending-byte (locking) page.
+#
+#   2) Open a backup process. Set the cache-size for the destination
+#      database to 10 pages only.
+#
+#   3) Step the backup process N times to partially backup the database
+#      file. If an IO error is reported, then the backup process is
+#      concluded with a call to backup_finish().
+#
+#      If an IO error occurs, verify that:
+#
+#      * the call to backup_step() returns an SQLITE_IOERR_XXX error code.
+#
+#      * after the failed call to backup_step() but before the call to
+#        backup_finish() the destination database handle error code and 
+#        error message remain unchanged.
+#
+#      * the call to backup_finish() returns an SQLITE_IOERR_XXX error code.
+#
+#      * following the call to backup_finish(), the destination database
+#        handle has been populated with an error code and error message.
+#
+#   4) Write to the database via the source database connection. Check 
+#      that:
+#
+#      * If an IO error occurs while writing the source database, the
+#        write operation should report an IO error. The backup should 
+#        proceed as normal.
+#
+#      * If an IO error occurs while updating the backup, the write 
+#        operation should proceed normally. The error should be reported
+#        from the next call to backup_step() (in step 5 of this test
+#        procedure).
+#
+#   5) Step the backup process to finish the backup. If an IO error is 
+#      reported, then the backup process is concluded with a call to 
+#      backup_finish().
+#
+#      Test that if an IO error occurs, or if one occurred while updating
+#      the backup database during step 4, then the conditions listed
+#      under step 3 are all true.
+#
+#   6) Finish the backup process.
+#
+#   * If the backup succeeds (backup_finish() returns SQLITE_OK), then
+#     the contents of the backup database should match that of the
+#     source database.
+#
+#   * If the backup fails (backup_finish() returns other than SQLITE_OK), 
+#     then the contents of the backup database should be as they were 
+#     before the operation was started.
+#
+# The following factors are varied:
+#
