# Paths to skeleton port's source & real Slackware source tree:

export PORTCWD=$PWD

# Temporary build locations:
export TMPBUILD=$TMP/build-$PACKAGE
export PKG=$TMP/package-$PACKAGE
mkpkgdirs # Delete & re-create temporary directories then cd into $TMPBUILD

# Determine the CFLAGS for the known architectures:
case $PORTARCH in

   powerpc) export SLKCFLAGS="-O2" ;;

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

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

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