Puppet module for apache

 Puppet lets you centrally manage every important aspect of your system
 using a cross-platform specification language that manages all the
 separate elements normally aggregated in different files, like users,
 cron jobs, and hosts, along with obviously discrete elements like
 packages, services, and files.
 .
 This module includes the ability to configure and manage a range of
 different virtual host setups, as well as a streamlined way to install
 and configure Apache modules.
