# Modifications made by GitHub.com/BassThatHertz:
# ----------------------------------------------------------------------------------------------------------------------
# - Added CPU clock speed (can't remember the exact source of the clock speed command)
# - Removed the "GPU temperature" after reading a comment by "onebuck" (on March 12th, 2016):
# https://www.cyberciti.biz/faq/linux-find-out-raspberry-pi-gpu-and-arm-cpu-temperature-command/
# A couple of quotes from their comment:
# "Your reading the same sensor for CPU when you say access to GPU."
# "GPU does not have a sensor independently. Just a CPU temperature can be truly accessed"
# - Other minor edits.
