-#
-# This is a simple package manager written in POSIX 'sh' for
-# KISS Linux utlizing the core unix utilites where needed.
-#
-# The script runs with 'set -e' enabled. It will exit on any
-# non-zero return code. This ensures that no function continues
-# if it fails at any point.
-#
-# Keep in mind that this involves extra code in the case where
-# an error is optional or required.
-#
-# Where possible the package manager should "error first".
-# Check things first, die is necessary and continue if all is well.
-#
-# The code below conforms to shellcheck's rules. However, some
-# lint errors *are* disabled as they relate to unexpected
-# behavior (which we do expect).
-#
-# KISS is available under the MIT license.
