# Record toolchain & other info for the build log:

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

# Temporary build locations:

# Build:
make $NUMJOBS || failmake

# Install into package:
make install DESTDIR=$PKG || failinstall

# Install some python-demo files:
mkdir -vpm755 $PKG/usr/doc/$PKGNAM-$VERSION/html
cp -favv Demo $PKG/usr/doc/$PKGNAM-$VERSION

# We'll install the python-tools under site-packages:
mkdir -vpm755 $SITEPK
( cd Tools ; cp -a * $SITEPK )
mkdir -vpm755 $PKG/usr/doc/$PKGNAM-$VERSION
mv -fv $SITEPK/README $PKG/usr/doc/$PKGNAM-$VERSION/README.python-tools
( cd $PKG/usr/doc/$PKGNAM-$VERSION
  ln -vsf $TOOLSDIR Tools )
# Make a few useful symlinks:
mkdir -vpm755 $PKG/usr/bin
( cd $PKG/usr/bin
  ln -vsf $TOOLSDIR/modulator/modulator.py modulator
  ln -vsf $TOOLSDIR/pynche/pynche pynche
  ln -vsf $TOOLSDIR/i18n/msgfmt.py .
  ln -vsf $TOOLSDIR/i18n/pygettext.py . )

# Replace hardlink with symlink:
( cd $PKG/usr/bin
  rm -fv python
  ln -vsf python2.5 python )

# Install docs:
cp -favv README Misc $PKG/usr/doc/$PKGNAM-$VERSION
tar xvvf $CWD/html-$VERSION.tar.bz2 -C${PKG}/usr/doc/$PKGNAM-$VERSION/html

# If necessary, start the fakeroot server so we can set file/dir ownerships:
start_fakeroot

# Apply generic Slackware packaging policies:
cd $PKG
slackstripall   # strip all .a archives and all ELFs
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
