In testing various gretl features using gretlcli I've sometimes wished for a way of setting a value within a script automatically via the command line (i.e. without having to edit the script). One can do that via environment variables, given gretl's getenv() function, but this can be a bit clunky. There's now a new command-line option "--switch=<value>". An integer value registered in this way is accessible via the internal variable $switch. In addition, since we have the GUI language selector now, the option -q or --basque seems redundant; now -q is paired with --quiet and gives less verbose program information on start-up.
