<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/bash
topic=$(echo "$1" | lowercase | sed 's/^\(an\?\|the\) //;s/s\?[:;,.!?]\? .*//')
[ -e "$HACKENV/wisdom/$topic" ] && verb="Relearned" || verb="Learned"
echo "$1" >"$(echo-p "$HACKENV/wisdom/$topic")"
echo "$verb '$topic': $1"
