# Overview:
#   This script compiles and install the Broadcom VideoCore tools,
#   configure the dynamic loader for the non-standard library location,
#   and update the loader cache.
#
#   A few steps explicitly requires root privilege, which are
#   marked with "sudo". The rest is just checking for duplicate/previous
#   action.
#
#   This derived from my command history on ubuntu 20.04.1 .YMMV
