Not really; pdfroff is just a shell script, which runs groff -Tps
multiple times, (to resolve internal pdfmark references), until the
layout stabilizes, then pipes the resultant PostScript output through
gs, to generate PDF output.  You might infer use of pdfroff from the
existence of a register called PHASE, (which will have a value of 1 when
compiling a relocatable TOC, and 2 in the final document body generating
pass), but that's hardly exclusive to pdfroff.
