You have to add `-e' to the command line to make groff call eqn:

  groff -ms -e example.txt > example.ps

Hmm.  There is a script called grog which guesses how to call groff
for a document:

  $ grog example.txt
  groff -e -ms example.txt

It then prints the calling sequence.  It's not completely reliable but
in most cases it works.

If you add the `-V' switch to groff it shows the pipeline of groff
commands:

  $ groff -V -ms -e example.txt
  eqn -Tps example.txt | troff -ms -Tps | grops

Which you could use as an alternative to see the various stages.

Finally, you might add the flag `-ww' to groff to see all warnings it
emits for your document.

There have been reports that eqn doesn't work correctly on the MAC if
incorrectly compiled.  Please check the mailing list archives for more
information.
