VCP::HeadRevsDB3pm

Usage

    use base qw( VCP::HeadRevsDB );

Overview

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.
