[CMI.PM] Perl Debugger and finding CPU Usage

[Sigfried Gold]

i've done this.  the perl profiler is pretty easy to use.

from perldoc perldebug:

          The Perl Profiler

          If you wish to supply an alternative debugger for Perl to
          run, just invoke your script with a colon and a package
          argument given to the -d flag.  The most popular alternative
          debuggers for Perl is the Perl profiler.  Devel::DProf is
          now included with the standard Perl distribution.  To
          profile your Perl program in the file mycode.pl, just type:

              $ perl -d:DProf mycode.pl

          When the script terminates the profiler will dump the
          profile information to a file called tmon.out.  A tool like
          dprofpp, also supplied with the standard Perl distribution,
          can be used to interpret the information in that profile.
