+"""Gather output from test runs and create an XML file in JUnit format.
+
+The output files from the individual tests have been written in a directory
+structure like:
+
+  $DIR/joblog  (--joblog from "parallel")
+  $DIR/logs/1/cpp/stdout
+  $DIR/logs/1/cpp/stderr
+  $DIR/logs/1/csharp/stdout
+  $DIR/logs/1/csharp/stderr
+  $DIR/logs/1/java_jdk7/stdout
+  $DIR/logs/1/java_jdk7/stderr
+  etc.
+
+This script bundles them into a single output XML file so Jenkins can show
+detailed test results.
