-1998 Nov 10 
-This version of DProf should work with older Perls too, but to get
-full benefits some patches to 5.004_55 are needed.  Patches take effect 
-after new version of Perl is installed, and DProf recompiled.
-
-Without these patches the overhead of DProf is too big, thus the statistic
-may be very skewed.

-=head1 NAME
-
-Devel::DProf - a B<DEPRECATED> Perl code profiler
-
-=head1 SYNOPSIS
-
-	perl -d:DProf test.pl
-
-=head1 ACHTUNG!
-
-C<Devel::DProf> is B<DEPRECATED> and will be removed from a future version of
-Perl. We strongly recommend that you install and use L<Devel::NYTProf> instead,
-as it offers significantly improved profiling and reporting.
-
-=head1 DESCRIPTION
-
-The Devel::DProf package is a Perl code profiler.  This will collect
-information on the execution time of a Perl script and of the subs in that
-script.  This information can be used to determine which subroutines are
-using the most time and which subroutines are being called most often.  This
-information can also be used to create an execution graph of the script,
-showing subroutine relationships.
-
-To profile a Perl script run the perl interpreter with the B<-d> debugging
-switch.  The profiler uses the debugging hooks.  So to profile script
-F<test.pl> the following command should be used:
-
-	perl -d:DProf test.pl
-
-When the script terminates (or when the output buffer is filled) the
-profiler will dump the profile information to a file called
-F<tmon.out>.  A tool like I<dprofpp> can be used to interpret the
-information which is in that profile.  The following command will
-print the top 15 subroutines which used the most time:
-
-	dprofpp
-
-To print an execution graph of the subroutines in the script use the
-following command:
-
-	dprofpp -T
-
-Consult L<dprofpp> for other options.
-
-=head1 PROFILE FORMAT
-
-The old profile is a text file which looks like this:
-
-	#fOrTyTwO
-	$hz=100;
-	$XS_VERSION='DProf 19970606';
-	# All values are given in HZ
-	$rrun_utime=2; $rrun_stime=0; $rrun_rtime=7
-	PART2
-	+ 26 28 566822884 DynaLoader::import
-	- 26 28 566822884 DynaLoader::import
-	+ 27 28 566822885 main::bar
-	- 27 28 566822886 main::bar
-	+ 27 28 566822886 main::baz
-	+ 27 28 566822887 main::bar
-	- 27 28 566822888 main::bar
-	[....]
-
-The first line is the magic number.  The second line is the hertz value, or
-clock ticks, of the machine where the profile was collected.  The third line
-is the name and version identifier of the tool which created the profile.
-The fourth line is a comment.  The fifth line contains three variables
-holding the user time, system time, and realtime of the process while it was
-being profiled.  The sixth line indicates the beginning of the sub
-entry/exit profile section.
-
-The columns in B<PART2> are:
-
-	sub entry(+)/exit(-) mark
-	app's user time at sub entry/exit mark, in ticks
-	app's system time at sub entry/exit mark, in ticks
-	app's realtime at sub entry/exit mark, in ticks
-	fully-qualified sub name, when possible
-
-With newer perls another format is used, which may look like this:
-
-        #fOrTyTwO
-        $hz=10000;
-        $XS_VERSION='DProf 19971213';
-        # All values are given in HZ
-        $over_utime=5917; $over_stime=0; $over_rtime=5917;
-        $over_tests=10000;
-        $rrun_utime=1284; $rrun_stime=0; $rrun_rtime=1284;
-        $total_marks=6;
-
-        PART2
-        @ 406 0 406
-        & 2 main bar
-        + 2
-        @ 456 0 456
-        - 2
-        @ 1 0 1
-        & 3 main baz
-        + 3
-        @ 141 0 141
-        + 2
-        @ 141 0 141
-        - 2
-        @ 1 0 1
-        & 4 main foo
-        + 4
-        @ 142 0 142
-        + & Devel::DProf::write
-        @ 5 0 5
-        - & Devel::DProf::write
-
-(with high value of $ENV{PERL_DPROF_TICKS}).  
-
-New C<$over_*> values show the measured overhead of making $over_tests
-calls to the profiler These values are used by the profiler to
-subtract the overhead from the runtimes.
-
-Lines starting with C<@> mark the amount of time passed since the
-previous C<@> line.  The numbers following the C<@> are integer tick
-counts representing user, system, and real time.  Divide these numbers
-by the $hz value in the header to get seconds.
-
-Lines starting with C<&> map subroutine identifiers (an integer) to
-subroutine packages and names.  These should only occur once per
-subroutine.
-
-Lines starting with C<+> or C<-> mark normal entering and exit of
-subroutines.  The number following is a reference to a subroutine
-identifier.
-
-Lines starting with C<*> mark where subroutines are entered by C<goto
-&subr>, but note that the return will still be marked as coming from
-the original sub.  The sequence might look like this:
-
-	+ 5
-	* 6
-	- 5
-
-Lines starting with C</> is like C<-> but mark where subroutines are
-exited by dying.  Example:
-
-	+ 5
-	+ 6
-	/ 6
-	/ 5
-
-Finally you might find C<@> time stamp marks surrounded by C<+ &
-Devel::DProf::write> and C<- & Devel::DProf::write> lines.  These 3
-lines are outputted when printing of the mark above actually consumed
-measurable time.
-
-=head1 AUTOLOAD
-
-When Devel::DProf finds a call to an C<&AUTOLOAD> subroutine it looks at the
-C<$AUTOLOAD> variable to find the real name of the sub being called.  See
-L<perlsub/"Autoloading">.
-
-=head1 ENVIRONMENT
-
-C<PERL_DPROF_BUFFER> sets size of output buffer in words.  Defaults to 2**14.
-
-C<PERL_DPROF_TICKS> sets number of ticks per second on some systems where
-a replacement for times() is used.  Defaults to the value of C<HZ> macro.
-
-C<PERL_DPROF_OUT_FILE_NAME> sets the name of the output file.  If not set,
-defaults to tmon.out.
-
-=head1 BUGS
-
-Builtin functions cannot be measured by Devel::DProf.
-
-With a newer Perl DProf relies on the fact that the numeric slot of
-$DB::sub contains an address of a subroutine.  Excessive manipulation
-of this variable may overwrite this slot, as in
-
-  $DB::sub = 'current_sub';
-  ...
-  $addr = $DB::sub + 0;
-
-will set this numeric slot to numeric value of the string
-C<current_sub>, i.e., to C<0>.  This will cause a segfault on the exit
-from this subroutine.  Note that the first assignment above does not
-change the numeric slot (it will I<mark> it as invalid, but will not
-write over it).
-
-Another problem is that if a subroutine exits using goto(LABEL),
-last(LABEL) or next(LABEL) then perl may crash or Devel::DProf will die
-with the error:
-
-   panic: Devel::DProf inconsistent subroutine return
-
-For example, this code will break under Devel::DProf:
-
-   sub foo {
-     last FOO;
-   }
-   FOO: {
-     foo();
-   }
-
-A pattern like this is used by Test::More's skip() function, for
-example.  See L<perldiag> for more details.
-
-Mail bug reports and feature requests to the perl5-porters mailing list at
-F<E<lt>perl5-porters@perl.orgE<gt>>.

-
-dprofpp B<-t> [B<-F>] [B<-g subroutine>] [profile]
-
-dprofpp B<-G> <regexp> [B<-P>] [profile]
-
-dprofpp B<-p script> [B<-Q>] [other opts]
-
-dprofpp B<-V> [profile]
-
-=head1 DESCRIPTION
-
-The I<dprofpp> command interprets profile data produced by a profiler, such
-as the Devel::DProf profiler.  Dprofpp will read the file F<tmon.out> and
-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 B<-d> switch.  So
-to profile script F<test.pl> with Devel::DProf use the following:
-
-	$ 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 L<Devel::DProf/"PROFILE FORMAT"> for a description of the raw profile.
-
-=head1 OUTPUT
-
-Columns are:
-
-=over 4
-
-=item %Time
-
-Percentage of time spent in this routine.
-
-=item #Calls
-
-Number of calls to this routine.
-
-=item sec/call
-
-Average number of seconds per call to this routine.
-
-=item Name
-
-Name of routine.
-
-=item CumulS
-
-Time (in seconds) spent in this routine and routines called from it.
-
-=item ExclSec
-
-Time (in seconds) spent in this routine (not including those called
-from it).
-
-=item Csec/c
-
-Average time (in seconds) spent in each call of this routine
-(including those called from it).
-
-=back
-
-=head1 OPTIONS
-
-=over 5
-
-=item B<-a>
-
-Sort alphabetically by subroutine names.
-
-=item B<-d>
-
-Reverse whatever sort is used
-
-=item B<-A>
-
-Count timing for autoloaded subroutine as timing for C<*::AUTOLOAD>.
-Otherwise the time to autoload it is counted as time of the subroutine
-itself (there is no way to separate autoload time from run time).
-
-This is going to be irrelevant with newer Perls.  They will inform
-C<Devel::DProf> I<when> the C<AUTOLOAD> switches to actual subroutine,
-so a separate statistics for C<AUTOLOAD> will be collected no matter
-whether this option is set.
-
-=item B<-R>
-
-Count anonymous subroutines defined in the same package separately.
-
-=item B<-E>
-
-(default)  Display all subroutine times exclusive of child subroutine times.
-
-=item B<-F>
-
-Force the generation of fake exit timestamps if dprofpp reports that the
-profile is garbled.  This is only useful if dprofpp determines that the
-profile is garbled due to missing exit timestamps.  You're on your own if
-you do this.  Consult the BUGS section.
-
-=item B<-I>
-
-Display all subroutine times inclusive of child subroutine times.
-
-=item B<-l>
-
-Sort by number of calls to the subroutines.  This may help identify
-candidates for inlining.
-
-=item B<-O cnt>
-
-Show only I<cnt> subroutines.  The default is 15.
-
-=item B<-p script>
-
-Tells dprofpp that it should profile the given script and then interpret its
-profile data.  See B<-Q>.
-
-=item B<-Q>
-
-Used with B<-p> to tell dprofpp to quit after profiling the script, without
-interpreting the data.
-
-=item B<-q>
-
-Do not display column headers.
-
-=item B<-r>
-
-Display elapsed real times rather than user+system times.
-
-=item B<-s>
-
-Display system times rather than user+system times.
-
-=item B<-T>
-
-Display subroutine call tree to stdout.  Subroutine statistics are
-not displayed.
-
-=item B<-t>
-
-Display subroutine call tree to stdout.  Subroutine statistics are not
-displayed.  When a function is called multiple consecutive times at the same
-calling level then it is displayed once with a repeat count.
-
-=item B<-S>
-
-Display I<merged> subroutine call tree to stdout.  Statistics are
-displayed for each branch of the tree.
-
-When a function is called multiple (I<not necessarily consecutive>)
-times in the same branch then all these calls go into one branch of
-the next level.  A repeat count is output together with combined
-inclusive, exclusive and kids time.
-
-Branches are sorted with regard to inclusive time.
-
-=item B<-U>
-
-Do not sort.  Display in the order found in the raw profile.
-
-=item B<-u>
-
-Display user times rather than user+system times.
-
-=item B<-V>
-
-Print dprofpp's version number and exit.  If a raw profile is found then its
-XS_VERSION variable will be displayed, too.
-
-=item B<-v>
-
-Sort by average time spent in subroutines during each call.  This may help
-identify candidates for inlining.
-
-=item B<-z>
-
-(default) Sort by amount of user+system time used.  The first few lines
-should show you which subroutines are using the most time.
-
-=item B<-g> C<subroutine>
-
-Ignore subroutines except C<subroutine> and whatever is called from it.
-
-=item B<-G> <regexp>
-
-Aggregate "Group" all calls matching the pattern together.
-For example this can be used to group all calls of a set of packages
-
-  -G "(package1::)|(package2::)|(package3::)"
-
-or to group subroutines by name:
-
-  -G "getNum"
-
-=item B<-P>
-
-Used with -G to aggregate "Pull" together all calls that did not match -G.
-
-=item B<-f> <regexp>
-
-Filter all calls matching the pattern.
-
-=item B<-h>
-
-Display brief help and exit.
-
-=item B<-H>
-
-Display long help and exit.
-
-=back
-
-=head1 ENVIRONMENT
-
-The environment variable B<DPROFPP_OPTS> can be set to a string containing
-options for dprofpp.  You might use this if you prefer B<-I> over B<-E> or
-if you want B<-F> on all the time.
-
-This was added fairly lazily, so there are some undesirable side effects.
-Options on the commandline should override options in DPROFPP_OPTS--but
-don't count on that in this version.
-
-=head1 BUGS
-
-Applications which call _exit() or exec() from within a subroutine
-will leave an incomplete profile.  See the B<-F> option.
-
-Any bugs in Devel::DProf, or any profiler generating the profile data, could
-be visible here.  See L<Devel::DProf/BUGS>.
-
-Mail bug reports and feature requests to the perl5-porters mailing list at
-F<E<lt>perl5-porters@perl.orgE<gt>>.  Bug reports should include the
-output of the B<-V> option.
