=head1 NAME
RefDB::Client - Perl extension for talking to a RefDB server
=head1 SYNOPSIS
use RefDB::Client;
=head1 DESCRIPTION
RefDB::Client provides functions to talk to a refdbd process like the RefDB C clients do. This module isn't a wrapper for the C clients but uses native Perl code to talk to the server.
