+
+# Purpose of this script is to build a VirtualBox or QCOW2 disk image
+# for use with CSIT testing.
+#
+# As input parameters, the script takes:
+#
+# - A base Linux distribution (currently, only "ubuntu-14.04.4" is
+#   supported),
+# - A release timestamp in the format "YYYY-MM-DD" eg. "2016-05-21".
+#   This timestamp MUST reference to a list of packages (APT, PIP)
+#   that was previously generated by the "listmaker" VM and script.
+# - A path to the nested VM image.
+#
+# The bullk of the work is done by packer,
+# while this script does some of the pre- and post-processing.
+# Steps executed are:
+#
+# 1.) Determine if building a QCOW or VirtualBox image. Currently,
+#     we build a QCOW image if VIRL_* environment variables are
+#     present (and we therefore assume we are building for VIRL),
+#     or VirtualBox otherwise.
+#
+# 2.) Download packer, if not already installed.
+#
+# 3.) Download APT and PIP packages as required for the image.
+#     We're downloading them here, rather than letting the VM
+#     download them off the public internet, for two reasons:
+#     a.) This allows us to keep and cache packets between runs
+#         and download them only once,
+#     b.) This means only the build host needs a working proxy
+#         configuration and we do not need to worry about setting
+#         a proxy inside the VM.
+#
+# 4.) Link the nested VM image into the main VM's temp directory
+#
+# 5.) Create Version and Changelog files
+#
+# 6.) Run Packer. Packer, in turn, will:
+#     6.1.) Download the Operating System ISO image,
+#     6.2.) Start a VM using the selected hypervisor (VirtualBox or Qemu),
+#     6.3.) Boot the VM using the ISO image and send initial keystrokes
+#           to initiate installation using a Preseed or Kickstart file,
+#     6.4.) Drive the installation using until the point the VM is reachable
+#           over SSH,
+#     6.5.) Copy the temporary directory populated in steps 3-5 above to the VM,
+#     6.6.) Run a script on the VM that performs post-installation:
+#           6.6.1.) Install selected .deb packages
+#           6.6.2.) Install PIP packages as per requirements.txt file
+#           6.6.3.) Install nested VM image and VERSION/CHANGELOG files
+#     6.7.) Run a script on VM that creates a Vagrant user (VirtualBox only)
+#     6.8.) Run a script on VM that performs clean-up:
+#           6.8.1.) Remove any temporary files created,
+#           6.8.2.) Remove SSH host-keys
+#           6.8.3.) Remove root user password
+#           6.8.4.) Shut down the VM
+#     6.9.) [TODO]: Upload the image to VIRL (QCOW only), -or-
+#           Convert the image into a Vagrant box (VirtualBox only), and
+#           [TODO/FIX]: Upload the Vagrant box to Atlas (VirtualBox only)
+#
+# 7.) Clean up
