=head1 NAME

Chirp::Stat - Perl Chirp file stat information, much like Unix C<< stat >>
structure.

=head1 SYNOPSIS

The objects and methods provided by this package correspond to the native C API
in chirp_types.h. This module is automatically loaded with C<< Chirp::Client >>.

Chirp::Stat objects are not be created directly, but instead are the result of
calling Chirp::Client::stat and Chirp::Client::ls.

head1 EXAMPLE

		use Chirp::Client;
		my $client = Chip::Client->new(localhost => 'localhost:9000');
		my $s = $client->stat('/myfile.txt');
		print $s->size, "\n";
