### copy some documentation files
mkdir -p $PKG/usr/doc/$PKGNAME-$VERSION
mv $PKG/usr/lib$LIBDIRSUFFIX/codecs/README \
  $PKG/usr/doc/$PKGNAME-$VERSION/README

cat $CWD/$PKGNAME.SlackBuild > $PKG/usr/doc/$PKGNAME-$VERSION/$PKGNAME.SlackBuild

### compress man pages
if [ -d $PKG/usr/man ]; then

### now you must do 'strip' all binary files
( cd $PKG
  find . | xargs file | grep "executable" | grep ELF | cut -f 1 -d : | xargs -r strip --strip-unneeded 2> /dev/null || true
  find . | xargs file | grep "shared object" | grep ELF | cut -f 1 -d : | xargs -r strip --strip-unneeded 2> /dev/null || true
  find . | xargs file | grep "current ar archive" | cut -f 1 -d : | xargs -r strip --strip-unneeded 2> /dev/null || true
)

### popolate the install/ directory
mkdir -p $PKG/install
cat $CWD/slack-desc > $PKG/install/slack-desc

### reset owner and create slack-required file.
cd $PKG
chown -R root:root $PKG

if [ -x "$(which requiredbuilder 2>/dev/null)" ];then
  requiredbuilder -y -v -s $CWD $PKG
fi

### finally make the package. 
/sbin/makepkg -l y -c n $OUTPUT/$PKGNAME-$VERSION-$ARCH-$BUILD.${PKGTYPE:-txz}

if [ "$1" = "--cleanup" ]; then
  rm -rf $TMP
fi
