<oerjan> le/rn scowrevs///hackenv/share/scowrevs is a list of repository revision ranges that affected a lot of files but in the end changed nothing (usually because of a revert at the end). Most of our custom repository lookup commands ignore these to reduce noise.

#!/bin/sh
topic=$(echo "$1" | tr A-Z a-z)
[ -e "wisdom/$topic" ] || { echo "$1? ¯\(°_o)/¯"; exit 1; }
cat "wisdom/$topic"
