package VCP::HeadRevsDB;
=head1 NAME
VCP::HeadRevsDB - Persistant storage for id -> (name, rev_id) maps
=head1 SYNOPSIS
use base qw( VCP::HeadRevsDB );
=head1 DESCRIPTION
By default, most VCP::Dest::* drivers keep track of the head revision
transferred to the destination for each branch of each file. This
is used by VCP::Source::* drivers when figuring out what revisions
to export in an incremental (or resumed) export..
The intent for this file is to serve as a base class so that individual
sites may write their own HeadRevsDB plugins to, for instance, store this
state in a RDBMS table. This is not quite offered at this time; we need
to add an option to the appropriate VCP::Dest::* modules to allow the
appropriate HeadRevsDB file to be loaded.
To write your own HeadRevsDB file, see VCP::HeadRevsDB::sdbm.
