# Optional: where to execute the run. Default is the current runarea
run-area /some/path/to/megatest/area

# Optional: method to use to determine pass/fail status of the run
#   auto (default) - roll up the net state/status of the sub-run
#   logpro         - use the provided logpro rules, happens automatically if there is a logpro section
# passfail auto|logpro
# Example of logpro:
passfail logpro

# Optional:
logpro ;; if this section exists then logpro is used to determine pass/fail

target #{shell somescript.sh}

# Optional: runname translator/generator, default is to use the parent runname
run-name #{somescript.sh}

# Optional: testpatt spec, default is to first look for TESTPATT spec from runconfigs unless there is a contour spec
test-patt %/item1,test2

# Optional: contour spec, use the named contour from the megatest.config contour spec
contour contourname ### NOTE: Not implemented yet! Let us know if you need this feature.

# Optional: mode-patt, use this spec for testpatt from runconfigs
mode-patt TESTPATT

# Optional: tag-expr, use this tag-expr to select tests
tag-expr quick
