# Test organization:
#
# alter-1.1.* - alter-1.7.*: Basic tests of ALTER TABLE, including tables
#     with implicit and explicit indices. These tests came from an earlier
#     fork of SQLite that also supported ALTER TABLE.
# alter-1.8.*: Tests for ALTER TABLE when the table resides in an 
#     attached database.
# 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.
#

# Create some tables to rename.  Be sure to include some TEMP tables
# and some tables with odd names.
