`Devel::DProf`

Here's the contents of tmon.out
First there's a header section with metainformation:

        #fOrTyTwO
        $hz=100;
        $XS_VERSION='DProf 20000000.00_01';
        # All values are given in HZ
        $over_utime=11; $over_stime=1; $over_rtime=12;
        $over_tests=10000;
        $rrun_utime=746; $rrun_stime=7; $rrun_rtime=800;
        $total_marks=33941

$hz is the clock resolution of the system
- Here one 'Hz' is 1/100 second
The $over_ variables try to record overhead of checking the clock
- (u == user time, s == system time, r == real (wallclock) time)
- For example, 11/10000 user-seconds per call
$rrun_ are the total times consumed by the sample run
$total_marks is the total number of subroutine entries and exits
