Is it only one kind of support or me can report this feature on some bugtracker?

Or there may be a way to run some script with python commands which can take args.

Like this :

sublime_text --script <file name> --script-arg <arg>[<arg>] [--script <file name> --script-arg <arg>[<arg>]]

Both of this features allow to make from sublime something like nice diff or/and merge tool, use it for automatic text processing and integrate it with some other products, such as IDE's may be .
