puts "Runs one or more JavaScript runtimes against SunSpider, V8, and/or Kraken"
puts "benchmarks, and reports detailed statistics. What makes run-jsc-benchmarks"
puts "special is that each benchmark/VM configuration is run in a single VM invocation,"
puts "and the invocations are run in random order. This minimizes systematics due to"
puts "one benchmark polluting the running time of another. The fine-grained"
puts "interleaving of VM invocations further minimizes systematics due to changes in"
puts "the performance or behavior of your machine."
puts
puts "Run-jsc-benchmarks is highly configurable. You can compare as many VMs as you"
puts "like. You can change the amount of warm-up iterations, number of iterations"
puts "executed per VM invocation, and the number of VM invocations per benchmark."
puts
puts "The <vm> should be either a path to a JavaScript runtime executable (such as"
puts "jsc), or a string of the form <name>:<path>, where the <path> is the path to"
puts "the executable and <name> is the name that you would like to give the"
puts "configuration for the purposeof reporting. If no name is given, a generic name"
puts "of the form Conf#<n> will be ascribed to the configuration automatically."
puts
puts "It's also possible to specify per-VM environment variables. For example, you"
puts "might specify a VM like Foo:JSC_useJIT=false:/path/to/jsc, in which case the"
puts "harness will set the JSC_useJIT environment variable to false just before running"
puts "the given VM. Note that the harness will not unset the environment variable, so"
puts "you must ensure that your other VMs will use the opposite setting"
puts "(JSC_useJIT=true in this case)."
puts
puts "Options:"
puts "--rerun <n> Set the number of iterations of the benchmark that"
puts " contribute to the measured run time. Default is #{$rerun}."
puts "--inner <n> Set the number of inner (per-runtime-invocation)"
puts " iterations. Default is #{$inner}."
puts "--outer <n> Set the number of runtime invocations for each benchmark."
puts " Default is #{$outer}."
puts "--warmup <n> Set the number of warm-up runs per invocation. Default"
puts " is #{$warmup}. This has a different effect on different kinds"
puts " benchmarks. Some benchmarks have no notion of warm-up."
puts "--no-ss-warmup Disable SunSpider-based warm-up runs."
puts "--quantum <n> Set the duration in milliseconds for which an iteration of"
puts " a throughput benchmark should be run. Default is #{$quantum}."
puts "--timing-mode Set the way that time is measured. Possible values"
puts " are 'preciseTime' and 'date'. Default is 'preciseTime'."
puts "--force-vm-kind Turn off auto-detection of VM kind, and assume that it is"
puts " the one specified. Valid arguments are 'jsc', "
puts " 'DumpRenderTree', or 'WebKitTestRunner'."
puts "--force-vm-copy Force VM builds to be copied to the working directory."
puts " This may reduce pathologies resulting from path names."
puts "--dont-copy-vms Don't copy VMs even when doing a remote benchmarking run;"
puts " instead assume that they are already there."
puts "--sunspider Only run SunSpider."
puts "--sunspider-compile-time"

puts "--compression-bench Only run compression bench"
puts " The default is to run all benchmarks. The above options can"
puts " be combined to run any subset (so --sunspider --dsp will run"
puts " both SunSpider and DSP)."
puts "--six-speed Only run SixSpeed."
puts "--benchmarks Only run benchmarks matching the given regular expression."
puts "--measure-gc Turn off manual calls to gc(), so that GC time is measured."

puts " --measure-gc <conf>, which turns this on for one"
puts " configuration only."
puts "--verbose or -v Print more stuff."
puts "--brief Print only the final result for each VM."
puts "--silent Don't print progress. This might slightly reduce some"
puts " performance perturbation."
puts "--remote <sshhosts> Perform performance measurements remotely, on the given"
puts " SSH host(s). Easiest way to use this is to specify the SSH"
puts " user@host string. However, you can also supply a comma-"
puts " separated list of SSH hosts. Alternatively, you can use this"
puts " option multiple times to specify multiple hosts. This"
puts " automatically copies the WebKit release builds of the VMs"
puts " you specified to all of the hosts."
puts "--ssh-options Pass additional options to SSH."
puts "--local Also do a local benchmark run even when doing --remote."
puts "--vms Use a JSON file to specify which VMs to run, as opposed to"

puts "--prepare-only Only prepare the runscript (a shell script that"
puts " invokes the VMs to run benchmarks) but don't run it."
