# The welcome message displayed when this scrip[t it first executed.
read -d '' WELCOME <<"EOF"
The ADS-B Project is a series of bash scripts and files which can be used to setup an ADS-B feeder on certain Debian derived operating system.

More information on the project can be found on GitHub.

Would you like to continue setup?
EOF

# Message displayed asking to update the operating system.
read -d '' UPDATEFIRST <<"EOF"
It is recommended that you update your system before building and/or installing any ADS-B feeder related packages. This script can do this for you at this time if you like.

Update system before installing any ADS-B feeder related software?
EOF

# Message displayed asking to update the Raspberry Pi firmware.
read -d '' UPDATEFIRMWAREFIRST <<"EOF"
This script has detected that this may be a Raspberry Pi. If this is in fact a Raspberry Pi this script can update the system's firmware now as well.

If you choose to update your Raspberry Pi firmware this script will check for the existance of the package rpi-update and install it if it is not install already. After confirming that rpi-update is installed it will be used to update your firmware.

Is this in fact a Raspberry Pi and if so do you want to update
the firmware now? (This will require a reboot.)
