" Input: {
(scenario) - UOA of a module with crowdsourcing scenario
(tags) - tags to prune experimental scenarios
(quiet) - do not ask questions, but select random ...
(skip_welcome) - if 'yes', do not print welcome header
(skip_exchange) - if 'yes', do not exchange platform info
(development mode)
(change_user) - if yes', change user
(local) - if 'yes', use local repo for exchange (local autotuning/benchmarking)
(exchange_repo) - which repo to record/update info (remote-ck by default)
(exchange_subrepo) - if remote, remote repo UOA
(once) - if 'yes', run scenario ones (useful for autotuning a given program)
}
Output: {
return - return code = 0, if successful
> 0, if error
(error) - error text if return > 0
Output of the last scenario (important for mobile device experiment crowdsourcing)
}
