Except that the "names" of the operators are those from PDF ;).

I completely agree with Aandi here!

You would be MUCH better off adding a new stream (remember
that a page can contain more than one stream) either before or after
the existing ones (depending on where you want your stuff to appear).

If you really do need to MODIFY the content (change a word,
color, etc.) then I would agree with Aandi - use PDFEdit (assuming
you can - not all PDFLibraries support it ;). However, if you are
adding new streams, Cos is easier.
