# shellcheck shell=bash
# Written by Wren Linux parts/command-hints.sh (data/command-hints.bash), as
# /usr/local/share/wren/command-hints.bash; ~/.bashrc loads it.
# A command that isn't installed anywhere: if a Wren Linux extra provides it
# (its "# status:" line names bin:NAME or file:/usr/local/bin/NAME), this
# says which script installs it. It only prints: it never installs or runs
# anything, and it looks up plain names only. Bash calls it only when no
# program of that name exists, so it never hides a real one. Anything else
# goes to Debian's command-not-found, if installed, as /etc/bash.bashrc does.
