# - The script `check-env-dep` uses process substitution which is **not** a standard `sh` feature!
#   See also: https://unix.stackexchange.com/questions/151925
# - The script `reformat-source` uses `command -v`, which is optional in POSIX. However, since `which` is not part of POSIX at all
#   `command -v` is probably the most portable solution to detect the location of a command.
