# FPP Install Script
#
# This is a quick and dirty script to take a stock OS build and install FPP
# onto it for use in building FPP images or setting up a development system.
#
# The script will automatically setup the system for the development
# version of FPP, the system can then be switched to a new version number
# or git branch for release.
#
#############################################################################
# To use this script, download the latest copy from github and run it as
# root on the system where you want to install FPP:
#
# wget -O ./FPP_Install.sh https://raw.githubusercontent.com/FalconChristmas/fpp/master/SD/FPP_Install.sh
# chmod 700 ./FPP_Install.sh
# sudo ./FPP_Install.sh
#
#############################################################################
# NOTE: This script is used to build the SD images for FPP releases.  Its
#       main goal is to prep these release images.  It may be used for othe
#       purposes, but it is not our main priority to keep FPP working on
#       other Linux distributions or distribution versions other than those
#       we base our FPP releases on.  Currently, FPP images are based on the
#       following OS images for the Raspberry Pi and BeagleBone Black:
#
#       Raspberry Pi
#           - URL: FIXME
#           - Image
#             - 
#           - Login/Password
#             - pi/raspberry
#
#       BeagleBone Black
#           - URL: https://rcn-ee.com/rootfs/bb.org/release/2014-05-14/
#           - Images
#             - bone-debian-7.5-2014-05-14-2gb.img
#             - BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img
#           - Login
#             - root (no password)
#
#       Other OS images may work with this install script and FPP on the
#       Pi and BBB platforms, but these are the images we are currently
#       targetting for support.
#
#############################################################################
# Other platforms which may be functioning with varying degrees:
#
#       ODROID C1
#           http://recombi.net/odroid-c1_deb-7.8/
#           - odroid-c1-debian-7.8-03-29-2014.img
#           - Login/Password
#             - root/odroid
#           - This image is very small and a lot of packages get installed
#             by FPP_Install.sh, so make sure you resize/expand the root
#             filesystem as per the information.txt file on recombi.net.
