#     This script uses a Raspberry Pi SBC to download the EspressoBin 
# Ubuntu 16.04 LTS server image, prepare a MicroSD card for the EspressoBin
# and export the image files to the MicroSD card.
# 
#     This script is the first step of configuring the EspressoBin.  It expects
# a Raspberry Pi running Raspbian connected to the internet.  The MicroSD card
# must have a single partition and must be formatted with a filesystem the RasPi
# can read and write.  The MicroSD card needs to be connected to the RasPi with
# a USB MicroSD reader.
