Hi Ralph,

Yes, but then you need to know which pages to print in beforehand.

I was/am considering that option too. But again, you need to do that
manually.

Yes, this is what I would like to do, since I am already running two
passes to cover cross-referincing. I am not sure how this is to be done,
though. And when I collect the toc-entries I set some formatting options
(font, size, indentation) which I would like to preserve.

As an example I have defined the .$0 macro which is (by default) called
from .sh:

  .\" Define macros to generate index from .sh and .+c entries
  .de $0
  .\" -- Set font in section headings (disabled)
  .ie \\$3<2 \{\
  .     nr PF 3\}
  .el .nr PF 1
  .(x
  .ti \\$3
  \\f\\n(PF \\$2 \\$1\\f1
  .)x
  ..

What would I need to do to store the relevant information in a separate
file (and retrieve it again)?
