3 # Wrapper for automating benchmarking runs.
4 # Usage: bench passes user group [script]
6 # ..where passes is the number of times to run each script; uid/gid
7 # gives credentials to use when running the script; and script is a
8 # simple wrapper around each actual benchmark tool (eg. see run.*),
9 # if this is ommited, all run.* scripts are used in turn.
11 # Each run.foo script should report a comma-separated-value list of
12 # benchmark results on stdout or fail with a non-zero exit code;
13 # unless the -i option is supplied in which case it should instead
14 # report a comma-separated-value list of column headers (for report
15 # generation purposes).
