* autfilt, dstar2tgba, ltl2tgba, ltlcross, ltldo learned to measure
cpu-time (as opposed to wall-time) using --stats=%R. User or
system time, for children or parent, can be measured separately by
adding additional %[LETTER]R options. A typical use-case is
"ltldo --stats='... %[c]R ...' ..." to measure the time spent in
the tool ran by ltldo, excluding that of ltldo. In all tools, the
difference between %r (wall-clock time) and %R (CPU time) can also
be used to detect unreliable measurements.
