+<!-- IMPORTANT!
+
+This is not a normal ant build file. You need to run it via the Eclipse
+AntRunner, like this Unix shell example:
+
+$ eclipse -nosplash -clean \
+  -configuration $PWD/autobuild/configuration \
+  -user $PWD/autobuild \
+  -data $PWD/autobuild \
+  -application org.eclipse.ant.core.antRunner \
+  -buildfile build.xml \
+  -Dplugin.path=/usr/lib/eclipse:/usr/share/eclipse/dropins/jdt
+
+Setting the -configuration, -user, and -data options are important in an
+automated build process where you don't want to clobber the default locations.
