# You can use this script by running the following, one line at a time:
#
# A="terminalforlife/miscellaneous/master/install%204.13.5_64-bit%20(Ubuntu)"
# wget -q "https://raw.githubusercontent.com/$A" -O /tmp/4.13.5_64-bit_${$}.tmp
# chmod u+x !$ && sudo !$ && rm !$ && unset A
#
# ...or do it manually, if you prefer.

# NOTE Wed 10 Jan 21:35:05 GMT 2018:

# This is now pretty much pointless. Perhaps somebody could use it as reference or
# as some sort of proof of concept.

#TODO - Rework this script as a kernel installer for many versions, per what's
#       available online, whether in the standard Ubuntu repositories or not.
