IIRC, define that symbol as a named parameter (with appropriate
default) to, say, @MySetup and @Use @MySetup.  Command line options
are consulted for overrides when a symbol is @Use'd (see calls to
HuntCommandOption in z06.c).

Consider the manual page example @PageType which is a named parameter
to @DocumentSetup.
