I'm sorry.  This is not what I meant to say.  I meant that it
processes my document and produces a dvi I can look at.  (But I did
notice indented paragraphs which shouldn't have been indented.)

So what should I do?

I found out (read: Stefan told me) that generating fewer source
specials works with that package.  Also, the package apparently can
be changed to just skip the source specials.  And then, I could
abstain from the syntax package.

Sorry for the line-noise.
