=head1 NAME
PCP::LogSummary - Perl interface for pmlogsummary(1)
=head1 SYNOPSIS
use PCP::LogSummary;
my $summary = new PCP::LogSummary($log, \@metrics, $start, $end);
=head1 DESCRIPTION
The PCP::LogSummary module is a wrapper around the Performance Co-Pilot
pmlogsummary(1) command.
Its primary purpose is to automate the production of post-processed
pmlogsummary data, in particular to automate the step where the
summarised data is imported into a spreadsheet for further anaylsis.
This has proven to often be an iterative process - done manually it
involves much cutting+pasting, and can be a significant time waster.
