# PS1 - Primary prompt displayed before each command
####################################################
# The PS1 prompt is constructed piece-by-piece by concatenating each
# component to the previous component. Parts of the prompt are colored
# conditionally based on what kind of user is logged in.
#
# Breakdown of PS1 components:
# [TTY#] [DATE TIME] [USER HOST] [(BRANCH) DIR] >
#
# Example of what the prompt should look like:
# [1] [2023-03-28 16:02:55] [user host] [(stable) /etc/portage] >
