As it happens, I needed to do this on Monday.  I sent a note off to the
troff guru where I used to work (whose name I won't give out, to protect
the innocent), and he sent me the following instructions:

-----
  We took the standard psdit prologue (/usr/lib/ps/psdit.pro) and created
  a landscape version named /usr/lib/ps/land.pro by changing the line:

  /xi {0 72 11 mul translate 72 resolution div dup neg scale 0 0 moveto

  to:

  /xi {90 rotate 72 resolution div dup neg scale 0 0 moveto

  The land.pro prologue is accessed by "psdit -p/land.pro".
------

The above-mentioned line is line number 8 in our psdit.pro file; your
milage may vary.

Note that you have to adjust your line length, page offset, header and
footer margins to understand the rotated page; as near as I can tell
there is no way to change troff's idea that a page is 11 inches long.
For the -ms macros, I use something like:

	.nr LL 10i
	.nr PO .5i
	.nr HM .5i
	.nr FM 3i
	.ll 10i
	.po .5i

Which gives half-inch margins all around.  Works great!
