# This is a little Slackware-specific tool used in some of the network
# related scripts to calculate network and broadcast addresses:
( cd $PKG/bin

  chmod 755 ipmask
)
install -vpm644 $CWD/ipmask.8 $PKG/usr/man/man8/

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
slack_delete_lafiles # delete usr/lib{,64}/*.la
#slackstriprpaths     # strip rpaths
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
slackhlinks     # search for any hard links
