Does SunOS have ditroff?

[Scott Weitzenkamp]

  I am having problems printing some man pages on SunOS 4.1.1.  We
have TranScript, too (I'm not sure what version, but we got it in
1989).  The man pages are for the ISIS Version 2.1 software from
Cornell University, and seem to need ditroff to print.  Here is an
example of part of the man pages that refused to print correctly with
"troff -t -man ISIS.3 | lpr -t":

	.SH LIBRARY FUNCTIONS

	The following are the ISIS manual pages included in section 3:

        .nf
        \bu ISIS    -- general introduction to ISIS
        \bu address -- address manipulation routines
        \bu bcast   -- basic broadcast interface
        \bu bcast_l -- extended broadcast interface
        \bu bypass  -- bypass broadcast interface
        \bu cl_dump -- making human-readible status dumps within ISIS

  Someone from Cornell told me that the .nf and \bu directives are
pretty vanilla stuff.  He said that it sounded like I was missing a
font file.  Is ditroff part of SunOS 4.1.1?  If so, where is it?  I
looked through the 4.1.1 CD-ROM, and did not see ditroff in any of the
categories.

  Help!
