 information about the way the Debian binary packages are built. The
 very extensive upstream documentation is shipped in

 Exim (v4) is a mail transport agent. exim4-config provides the configuration
 for the exim4 daemon packages. The configuration framework has been split
 off the main package to allow sites to replace the configuration scheme
 with their own without having to change the actual exim4 packages.
 .
 Sites with special configuration needs (having a lot of identically
 configured machines for example) can use this to distribute their own
 custom configuration via the packaging system, using the magic
 available with dpkg's conffile handling, without having to do local
 changes on all of these machines.
