Re: (dsssl) rules in headers/footers

[curt brune <curt@xxxxxxxxxxxxxxxxx>]

OK I started reading the ISO/IEC 10179:1996 spec.  I now see I need to choose 
an orientation that results in the rule being inlined, i.e. the orientation 
needs to be either "escapement" or "line-progression".  I tried using the 
following:

(define (page-center-footer gi)
    (make rule
      orientation: 'escapement
      length: 7in
      line-thickness: 1pt
    )
)

But I get a *vertical* rule in my footer, not a horizontal rule.  Sigh.  I
was encouraged that I figured out how to make an inline rule, too.  I also
tried it with an orientation of line-progression, but I get the same results.

Is there some other orientation that results in an "inlined, horizontal" rule?
I did not see any other characteristics that looked promising. 

Cheers,
Curt
