Overview

Knows the following RPM fields:

name        Package name (mandatory)
version     Version (mandatory)
release     Release
summary     Short one-line description of package (mandatory)
description Description
packager    Name of the packager (defaults to the name of the user or 
            $USER@$HOSTNAME if not found)
license     License (defaults to GPL)
require     Array of required packages
make        Controls the build process:
              null    Search the top-level directory for configure or
                      make files and runs them. Skip building if not 
                      found. This is the default
              true    Expect the top-level directory to contain 
                      configure or make files and runs them. It is an 
                      error if the Makefile is missing
              (array of commands)
                      Runs the commands to build the project

Each field has a dynamically generated accessor method that can be referenced in the template file
