# Kali environment setup script intended to create a more
# full-featured, dev-friendly environment for those of us
# who prefer never touching the mouse. Naturally I can't do
# anything about the non-terminal based tools, this script simply
# applies a number of improvements to the system environment while
# in a terminal.
