#make test || failmake

# Install into package framework:
make install DESTDIR=$PKG || failinstall
# We put symlinks in /bin since some things still expect '/bin/mail' or '/bin/Mail':
mkdir -p $PKG/bin
( cd $PKG/bin
  ln -sf /usr/bin/mailx Mail
  ln -sf /usr/bin/mailx mail
  ln -sf /usr/bin/mailx nail )

# Likewise, we make some compat symlinks in /usr/bin:
( cd $PKG/usr/bin
  ln -sf mailx Mail
  ln -sf mailx mail
  ln -sf mailx nail )
mv -fv $PKG/etc/nail.rc $PKG/etc/nail.rc.new

# Manpage links:
( cd $PKG/usr/man/man1
  ln -sf mailx.1 mail.1
  ln -sf mailx.1 nail.1
  ln -sf mailx.1 Mail.1 )

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall        # strip all .a archives and all ELFs
#slackstriprpaths     # strip rpaths
slack_delete_lafiles # delete usr/lib{,64}/*.la
slackgzpages -i      # compress man & info pages and delete usr/info/dir
slackslack           # set standard Slackware file/dir permissions and ownerships
slackdesc            # install slack-desc and doinst.sh

# Tighten up the perms a bit:
chmod 4711 $PKG/usr/libexec/mailx-dotlock

slackmp         # run makepkg -l y -c n

# Perform any final checks on the package:
cd $PKG
slackhlinks     # search for any hard links
