Hi, I've checked in an update to the runtime parameters handling subsystem. It's not completely up to my liking yet, but should fare better than old one. From usage prospective you will see major differences in features supported by command line argument parser (don't worry - everything is backward compatible). New command line arguments parser allows: a) double identification for parameters (is not used for all parameters, but most). For example: "--log_level=<value>" and "-l <value>" for log level b) name guessing for long names. For example "--log_l=<value>" and "--log_le=<value>" will work fine Note though that --log_=<value> will produce an error message complaining about ambiguity, since there are two parameters - --log_level and --log_format that may fit. c) boolean parameters does not require the value. For example "--catch_system_errors" will work fine Parameter --random can be used without any value as well. d) New parameter --help,-? is supported that produces help message with usage information. Note that usage information is being printed also in case there was error parsing command line. Any comments and suggestions appreciated, Gennadiy
