dprofpp

markjuszczec has asked for the wisdom of the Perl Monks concerning the following question:

Oh monks, wise in the ways of Perl, I'm trying to use dprofpp. I've downloaded, installed and run DProf on a script to generate a tmon.out file. When I try to use dprofpp to format it, I get a syntax error if I do it from the debugger. The only references I can find in the documentation say things like "run dprofpp." Where do I find out how to run dprofpp? your unworthy acolyte Mark

NAME
       dprofpp - display perl profile data

SYNOPSIS
       dprofpp [-a|-z|-l|-v|-U] [-s|-r|-u] [-q] [-F] [-I|-E] [-O
       cnt] [-A] [-R] [-S] [-g subroutine] [profile]

       dprofpp -T [-F] [-g subroutine] [profile]

       dprofpp -t [-F] [-g subroutine] [profile]

       dprofpp -p script [-Q] [other opts]

       dprofpp -V [profile]

DESCRIPTION
       The dprofpp command interprets profile data produced by a
       profiler, such as the Devel::DProf profiler.  Dprofpp will
       read the file tmon.out and will display the 15 subroutines
       which are using the most time.  By default the times for
       each subroutine are given exclusive of the times of their
       child subroutines.

       To profile a Perl script run the perl interpreter with the
       -d switch.  So to profile script test.pl with Devel::DProf
       the following command should be used.

               $ perl5 -d:DProf test.pl

       Then run dprofpp to analyze the profile.  The output of
       dprofpp depends on the flags to the program and the
       version of Perl you're using.

               $ dprofpp -u
               Total Elapsed Time =    1.67 Seconds
                        User Time =    0.61 Seconds
               Exclusive Times
               %Time Seconds     #Calls sec/call Name
                52.4   0.320          2   0.1600 main::foo
                45.9   0.280        200   0.0014 main::bar
                0.00   0.000          1   0.0000 DynaLoader::import
                0.00   0.000          1   0.0000 main::baz

       The dprofpp tool can also run the profiler before
       analyzing the profile data.  The above two commands can be
       executed with one dprofpp command.

               $ dprofpp -u -p test.pl

       Consult the PROFILE FORMAT entry in the Devel::DProf
       manpage for a description of the raw profile.

The rest can be retrieved using 'perldoc dprofpp'. 'perldoc -f dprofpp' doesn't work.
