## ----------------------------------------------------------------------------
# Mostly this script takes care of testing the items exported by the 3
# tags below (in this order):
# - :sql_types
# - :squl_cursor_types
# - :util
# It also then handles some other class methods and functions of DBI, such
# as the following:
# - $DBI::dbi_debug & its relation to DBI->trace
# - DBI->internal
# and then tests on that return value:
# - $i->debug
# - $i->{DebugDispatch}
# - $i->{Warn}
# - $i->{Attribution}
# - $i->{Version}
# - $i->{private_test1}
# - $i->{cachedKids}
# - $i->{Kids}
# - $i->{ActiveKids}
# - $i->{Active}
# - and finally that it will not autovivify
# - DBI->available_drivers
# - DBI->installed_versions (only for developers)
