Hi Bill,

dh-cruft is a debhelper addon used extensively by the Games Team
to register the highscore files stored in /var/games/.

It does what the manually written postrm did and a bit more.

Here's for example the result for toppler:


  $ cat debian/toppler/DEBIAN/postrm
  #!/bin/sh
  set -e
  # Automatically added by dh_cruft/0.9.80
  if [ "$1" = "purge" ]
  then
      # we need to glob, so no quotes
      rm -rf ${DPKG_ROOT:-}/var/games/toppler/
      if test -d ${DPKG_ROOT:-}/var/games/
      then
         rmdir --ignore-fail-on-non-empty ${DPKG_ROOT:-}/var/games/
      fi
  fi
  # End automatically added section
  # Automatically added by dh_installmenu/13.31
  if [ -x "`command -v update-menus`" ] && [ -x "$DPKG_ROOT`command -v update-menus`" ]; then update-menus ; fi
  # End automatically added section


As a side-effect dh-cruft also register these volatiles files in the database
used by cruft-ng to know which files belong to which package;
but if you don't use cruft this won't be of interrest to you I guess.



Greetings

Alexandre
