This directory is a place holder for a user registration web application. There is no generic version of this application, but the Cipres source code repository contains a Cipres specific version. The pom.xml in this directory will build the cipres specific version when it is checked out to ${build.dir}/rest/restusers. The reason for having the pom.xml here instead of in the cipres repo with the code is that someday we may split our registration app into generic and cipres specific parts, as we've done with sdk and portal and the generic part will be in this directory.
