# Remove WAY TOO LARGE (and misplaced) docs:
# This can be fixed with "docdir=/usr/doc/$PKGNAM-$VERSION" passed to make
# but there's not really a good reason to do that given they'll be removed
rm -rf $PKG/usr/docs

  For a ton of additional documentation (too large to include
  here) on writing source code that uses libdb$PKGNAM, please see
  the original source tarball db-$VERSION.tar.!(*sign|*asc|*sig), which can be found
  on Oracle's web site:

# 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
