sampling interval used in time profiling.

info which can be mangled by \tr{hp2ps} and viewed with \tr{ghostview}
(or equivalent).

-The \tr{-p} option produces a standard {\em time profile} report.
+The \tr{-p?} option produces a standard {\em time profile} report.
It is written into the file \pl{<program>}\tr{.prof}.

actual time and allocation data as well. (Not used much.)

+The \tr{-P?} option also produces {\em serial time-profiling}
information, in the file \pl{<program>}\tr{.time}. This can be
converted into a (somewhat unsatisfactory) PostScript graph using
\tr{hp2ps} (see \Sectionref{hp2ps}).
