+# Setting up VirtualBox.
+# This script setups all necessary things to do a complete deployment of
+# VirtualBox player based live systems.
+#
+# The script tests for boot parameter of
+# live-config.virtualbox=ACTION:IMAGEPATH:VDINAME
+#
+# ACTION: The operation to perform on the workstation (none|scratch)
+# IMAGEPATH: The folder path to the Virtual image you want to run.
+# VDINAME: The name of the Virtual image you want to run.
+#
+# Notes:To use this file with VirtualBox images you will need to have a few things
+# setup:
+#
+# 1. VirtualBox needs to be installed with virtualbox-qt and virtualbox-dkms.
+# 2. This script tests for a partition names for writing image data and is used as
+#    scratch space. This scratch space should be a file system with linux permissions
+#    such as ext2.
+# 3. VM image(s) should be in a mounted folder and setup as follows:
+#    - Image(s) set to snapshot mode.
+#    - For each image, the image folder needs to have a file called
+#      image-release with a variable CRELEASE. An example: CRELEASE="1.0.0"
+#
+# The image-release file is used by the image maintainer and this script to tell
+# workstation(s) using a given image, to erase locally stored Virtual image files
+# and setup with the newly configure image. The operation of erasing locally
+# stored Virtual image files, is referred to as a scratch.
