5.002 beta 1

If you're adventurous, have a look at

    ftp://ftp.sems.com/pub/outgoing/perl5.0/perl5.002beta1.tar.gz

Many thanks to Andy for doing the integration.

Obviously, if you consult the bugs database, you'll note there are
still plenty of buglets that need fixing, and several enhancements that
I've intended to put in still haven't made it in (Hi, Tim and Ilya).
But I think it'll be pretty stable.  And you can start to fiddle around
with prototypes (which are, of course, still totally undocumented).

Packrats, don't worry too much about readvertising this widely.
Nowadays we're on a T1 here, so our bandwidth is okay.

Have the appropriate amount of jollity.

Larry

-=head1 NAME
-
-Devel::DProf - a Perl code profiler
-
-=head1 SYNOPSIS
-
-	PERL5DB="use Devel::DProf;"
-	export PERL5DB
-
-	perl5 -d test.pl
-
-=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 use this package the PERL5DB environment variable must be set to the
-following value:
-
-	PERL5DB="use Devel::DProf;"
-	export PERL5DB
-
-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
-"test.pl" the following command should be used:
-
-	perl5 -d test.pl
-
-When the script terminates the profiler will dump the profile information
-to a file called I<tmon.out>.  The supplied I<dprofpp> tool 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 the "dprofpp" manpage for other options.
-
-=head1 BUGS
-
-If perl5 is invoked with the B<-w> (warnings) flag then Devel::DProf will
-cause a large quantity of warnings to be printed.

-=head1 NAME
-
-dprofpp - display perl profile data
-
-=head1 SYNOPSIS
-
-dprofpp [B<-a|-t|-l|-v|-U|-T>] [B<-s|-r|-u>] [B<-q>] [B<-F>] [B<-O cnt>] [profile]
-
-=head1 DESCRIPTION
-
-The I<dprofpp> command interprets a profile file produced by the Devel::DProf
-profiler.  By default dprofpp will read the file I<tmon.out> and will display
-the 15 subroutines which are using the most time.
-
-=head1 OPTIONS
-
-=over 5
-
-=item B<-a>
-
-Sort alphabetically by subroutine names.
-
-=item B<-t>
-
-(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<-l>
-
-Sort by number of calls to the subroutines.  This may help identify
-candidates for inlining.
-
-=item B<-v>
-
-Sort by average time spent in subroutines during each call.  This may help
-identify candidates for inlining. 
-
-=item B<-U>
-
-Do not sort.  Display in the order found in the raw profile.
-
-=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<-T>
-
-Display subroutine call tree to stdout.  Subroutine statistics are
-not displayed.
-
-=item B<-q>
-
-Do not display column headers.  Does nothing if B<-T> is used.
-
-=item B<-O cnt>
-
-Show only I<cnt> subroutines.  The default is 15.  Does nothing if B<-T>
-is used.
-
-=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<-u>
-
-Display user times rather than user+system times.
-
-=back
-
-=head1 BUGS
-
-Applications which call I<die> from within an eval for exception handling
-(catch/throw) or for setjmp/longjmp may not generate a readable profile.
-
-Applications which call I<exit> from within a subroutine will leave an
-incomplete profile.
