+# This script is an example of how you can run blender from the command line
+# (in background mode with no interface) to automate tasks, in this example it
+# creates a text object, camera and light, then renders and/or saves it.
+# This example also shows how you can parse command line options to scripts.
+#
+# Example usage for this test.
+#  blender --background --factory-startup --python $HOME/background_job.py -- \
+#          --text="Hello World" \
+#          --render="/tmp/hello" \
+#          --save="/tmp/hello.blend"
+#
+# Notice:
+# '--factory-startup' is used to avoid the user default settings from
+#                     interfearing with automated scene generation.
+#
+# '--' causes blender to ignore all following arguments so python can use them.
+#
+# See blender --help for details.
