# kiss - package manager for kiss linux.
|
||||
# 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.
