# If libargon2 and libjson-c are both under /usr, there's very little reason to
# move this. This continues a trend generally going on with Linux based OSes to
# ignore weird /usr-is-a-separate-partition corner cases.
## Move the shared library to $PKG/lib${LIBDIRSUFFIX}:
#mkdir -p $PKG/lib${LIBDIRSUFFIX}
#( cd $PKG/usr/lib${LIBDIRSUFFIX}
#  for file in lib*.so.*.* ; do
#    mv $file ../../lib${LIBDIRSUFFIX}
#    ln -sf ../../lib${LIBDIRSUFFIX}/$file .
#  done
#  cp -a lib*.so.? ../../lib${LIBDIRSUFFIX}
#))

# Move the cryptsetup binary to $PKG/sbin:
mkdir -p $PKG/sbin
( cd $PKG/usr/sbin
  mv -fv cryptsetup ../../sbin
  ln -vsf ../../sbin/cryptsetup .
)

# Add the rc script:
mkdir -p $PKG/etc/rc.d
install -vpm755 $CWD/rc.luks $PKG/etc/rc.d/rc.luks.new

# Copy docs:
mkdir -p $PKG/usr/doc/$PKGNAM-$VERSION
cp -a \
  AUTHORS* COPYING* INSTALL* NEWS* README* TODO* FAQ* \
  $PKG/usr/doc/$PKGNAM-$VERSION
changelogliposuction ChangeLog $PKGNAM $VERSION # Trim down a "ChangeLog" file

# Convert pdf files to text. We do not package bloated PDFs.
( cd docs
  for file in *.pdf ; do
    pdftotext $file
  done
)
cp -fav docs/*.txt $PKG/usr/doc/$PKGNAM-$VERSION
cp -fav docs/v${VERSION}-ReleaseNotes $PKG/usr/doc/$PKGNAM-$VERSION

# Copy Slackware's crypttab manpage to package:
mkdir -p $PKG/usr/man/man5
install -vpm644 $CWD/crypttab.5 $PKG/usr/man/man5/

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
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
slackhlinks     # search for any hard links
