#% SYNOPSIS
#+ ${SCRIPT_NAME} [-hv]
#%
#% DESCRIPTION
#% This script generates new VNC server and SSH server and client keys and restores
#% certain ham radio application configurations to default values at boot time
#% if a file named DO_NOT_DELETE_THIS_FILE file does not exist in the user's
#% home directory.
#%
#% Run this script whenever the Pi boots by adding a crontab entry, like this:
#%
#% 1) Run crontab -e
#% 2) Add the following line to the end:
#%
#% @reboot sleep 5 && /usr/local/bin/initialize-pi.sh
#%
#% 3) Save and exit the crontab editor
#%
#% OPTIONS
#% -h, --help Print this help
#% -v, --version Print script information
