( cd $PKG/usr/sbin
  mv -fv cryptsetup ../../sbin
  ln -vsf ../../sbin/cryptsetup .

# Apply generic Slackware packaging policies:

slack_delete_lafiles # delete usr/lib{,64}/*.la
slackgzpages -i # compress man & info pages and delete usr/info/dir
slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh
slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
