# Note that suites and subsuites must exist in the database _before_ attempting
# insertion of results. This is intentional! You should think carefully about
# your [suite -> subsuite -> benchmark] hierarchy and definitions. These should
# be stable over time (especially for suites and subsuites) to facilitate
# long-term comparisons.
#
# These can be inserted using the benchmark client, through the "insert suite"
# and "insert subsuite" commands. Ask for help if you have questions.
