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.
