Hi Colin, I got around to testing your branch and the tool seem to work as advertised. Indeed, performance is a lot better with this tool compared to "man --recode". I have committed support for debhelper transparently using man-recode when present instead of "man --recode" to master (closing this bug). Please upload man-db with man-recode to Debian unstable at your convenience. :) Thanks, ~Niels
