=head1 NAME
SVN::SVNLook - Perl wrapper to the svnlook command.
=head1 SYNOPSIS
use SVN::SVNLook;
my $revision = 1;
my $svnlook = SVN::SVNLook->new(repo => 'repo url',
cmd => 'path to svn look');
my ($author,$date,$logmessage) = $svnlook->info(revision => $revision);
print "Author $author\n";
print "Date $date\n";
print "LogMessage $logmessage\n";
=head1 DESCRIPTION
SVN::SVNLook runs the command line client. This module was created to
make adding hooks script easier to manipulate.

=head1 METHODs
=head2 youngest
youngest ();
Perform the youngest command on the repository.
Returns the revision number of the most recent revision as a scalar.
=head2 info
info (revision=>$revision);
Perform the info command, for a given revision or transaction using
named parameters, or a single parameter will be assumed to mean
revision for backwards compatibility. The information returned is an
array containing author, date, and log message. If no $revision is
specified, info for the youngest revision is returned.
=head2 author
author (revision=>$revision);
Perform the author command, for a given revision or transaction using
named parameters or a single parameter will be assumed to mean
revision for backwards compatibility. The information returned is the
author message. If no $revision or transaction is specified, author
for the youngest revision is returned.
=head2 dirschanged
dirschanged (revision=>$revision)
Performs the dirs-changed command, for a given revision or transaction
using named parameters, or a single parameter will be assumed to mean
revision for backwards compatibility. This method returns a boolean and
an array reference.
=head2 fileschanged
fileschanged (revision=>$revision)
Performs the changed command, for a given revision or transaction
using named parameters or a single parameter will be assumed to mean
revision for backwards compatibility this method returns 3 array
references added, deleted and modified.
=head2 diff
diff (revision=>$revision)
Performs the diff command, for a given revision or transaction using
named parameters or a single parameter will be assumed to mean
revision for backwards compatability this method returns a hash
reference, with each file being the key and value being the diff info.
