[net.text] ditroff - nroff

sxs@lanl.ARPA (04/30/85)

We are using a program to generate indexes using ditroff.  
The program uses the .sy command of ditroff.
We would like to make indexes using nroff as well as ditroff,
  but .sy does not exist on our version of nroff.
Does anyone have a version of nroff that implements the .sy command?
