The information option ‘-Zabc’ prints to the screen the default contents of the style-file parameters beginning with ‘abc’. Just ‘-Z’ prints everything.
After printing the defaults, the ‘-p’ options (see -p) and the style file fweb.sty are processed. If that processing has overridden any of the defaults, the parameters are printed again, preceded by an asterisk.
To see only the parameters that have been modified from the defaults, say ‘--Z’.
The ‘-Z’ option behaves slightly differently for color escape sequences than for other parameters; see Color.
