+    Checks out to a directory '../$branch' shared between builds. Then creates
+    a directory 'build' for this job to build in, and 'src' which is a link to
+    the shared sources. This relies on all builds for the same branch being
+    serialised with lock so that one build doesn't update the sources while
+    another is building them.

+        <checkout branch="branches/WX_2_8_BRANCH"/>
