The ant-sf buildfile supplements tasks provided by the Ant-Salesforce JAR. The JAR provides a core set of tasks for retrieving and deploying metadata between Salesforce orgs. This buildfile provides a structured set of targets that are easy-to-use from the command line, or from a build server, like Bamboo, Jenkins, or TeamCity.
