+# 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.
