# Apply generic Slackware packaging policies:
cd $PKG

slackslack      # chown -R root:root, chmod -R og-w, slackchown, slack644docs
slackdesc       # install slack-desc and doinst.sh

# Build the package:

  else
   makepkg -l y -c n $PKGSTORE/$PKGSERIES/$PACKAGE-$VERSION-$ARCH-$BUILD.tgz

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