Sergey, the patch forces Jitrino help message on arbitrary cmd-line, even when no help requested.

>                 URL: http://issues.apache.org/jira/browse/HARMONY-2381
>             Project: Harmony
>          Issue Type: Improvement
>          Components: DRLVM

> It is proposed to extend Jitrino help with the following commands:
> -Djit.help=<action>
> 	will produce help for the action specified
> -Djit.help=jit
> 	will produce new info on current configuration
> -Djit.help=all
> 	will produce current help + configuration info
> -Djit.help=<anything other>
> 	will produce current help
> Help info on current confuguration will be composed in the following way.
> For each jit available, its name is printed:
> Jit <jit name>
> Further, for each pipeline defined in this jit, its name and filter 
> expression are printed:
>   Pipeline <pipeline name> filter <filter expression>
> For common pipeline, <common> is printed instead of name and no filter 
> clause is printed, because common pipeline has no name and has empty 
> filter. If pipeline has any pipeline-wide arguments (i.e. arguments that
> affect all actions in the pipeline), they are printed directly after
> pipeline name. 
>     arg <arg name>=<arg value>
> In a similar way, all enabled pipeline-wide streams (if any) are printed
>     stream <stream name> file <file name mask>
> Because different streams can have the same name, stream index is 
> printed after the name, so ct[1] and ct[2] are different streams with 
> the same name.
> If jit has non-empty list of enabled actions, it is printed next, one 
> action per line under "Actions" header:
>     Actions
>       <action full name>
> For each action which has specific arguments or streams enabled, 
> they are printed in the form similar to pipeline-wide arguments and 
> streams.
> For Jitrino.Jet, list of actions is not printed, because this jit 
> does not have any actions.
