#***********************************************************************
#
# The focus of this file is testing the CLI shell tool. Specifically, 
# testing that it is possible to run a ".dump" script that creates
# virtual tables without explicitly disabling defensive mode.
#
# And, that it can process a ".dump" script that contains strings
# delimited using double-quotes in the schema (DQS_DDL setting).
#

# Test plan:
#
#   shell1-1.*: Basic command line option handling.
#   shell1-2.*: Basic "dot" command token parsing.
#   shell1-3.*: Basic test that "dot" command can be called.
#   shell1-{4-8}.*: Test various "dot" commands's functionality.
#   shell1-9.*: Basic test that "dot" commands and SQL intermix ok.
