+<!-- START SNIPPET: ant-bootstrap
+
+By default the bootstrap will use ~/.m2/repository as the integration repository but you can define the integration 
+repository by specifying a property on the command line:
+
+ant -Dmaven.repo.local=/my/integration/repository
+
+Those familiar with Maven will note this is the same way the local repository can be set from the command-line. 
+This facilitates having a set of builds converge on the same repository for integration purposes.
