+# This serves as an alternative to "init functions". So the objective is to display
+# an abstract about what a script is doing in the background and delivering a status.
+# E.g.:
+#   - lnbegin "Doing awesome stuff"
+#   - do-something -q 2>/dev/null
+#   - case "$?" in
+#       0) lnok ;;
+#       255) lnwarn "Something uncritical went wrong" ;;
+#       *) lnfail "kaboom!" 101;;
+#     esac
+# 
+# This script uses unicode characters. A "legacy" variant where we fall back
+# to having e.g. "[ OK ]" instead of a checkmark is planned. (Earlier versions had that, too.)
+#
+# For a demo of the looks, use SCRIPTNAME -d.
