I'd expected the "resulttool log" command would default to generating the log files the store command generates into the current working directory, maybe printing to stdout a list of the files its created. It doesn't currently do this. If viewing a specific file was required, that could be an extra parameter specifying to log file to view? The "write" behavior could trigger off the command "resulttool log write X" where X was the output directory instead of cwd?
