package IPC::Run3::ProfLogger;
$VERSION = 0.043;
=head1 NAME
IPC::Run3::ProfLogger - write profiling data to a log file
=head1 SYNOPSIS
use IPC::Run3::ProfLogger;
my $logger = IPC::Run3::ProfLogger->new; ## write to "run3.out"
my $logger = IPC::Run3::ProfLogger->new( Destination => $fn );
$logger->app_call( \@cmd, $time );
$logger->run_exit( \@cmd1, @times1 );
$logger->run_exit( \@cmd1, @times1 );
$logger->app_exit( $time );
=head1 DESCRIPTION
Used by IPC::Run3 to write a profiling log file. Does not
generate reports or maintain statistics; its meant to have minimal
overhead.
Its API is compatible with a tiny subset of the other IPC::Run profiling
classes.
