# A note on bash code style (specifically if's)
# - No attempt to be POSIX-compliant, it's Bash (4.x+) here
# - In if's, use [[ instead of [; BUT quote strings around and next to ${{ }}
#   expansions because inside those expansions strings must always be quoted
# - Quotes: use "" only where shell "$VARIABLES" should be expanded;
#   ${{ }} is expanded before feeding the script to Bash, therefore single
#   quotes or even absense of any are enough '${{ }}' (but see above re if's)
