If you have nose and setuptools on your system you can execute the .rst files
in the examples directory by doing something like this::

  cd pyrun-checkoutdir && python pyrun.py -m nose.core nose/and/setuptools/under/here -v --with-doctest --doctest-extension=.rst -w examples

  # or
  cd pyrun-trunk
  python pyrun.py -C `which nosetests` lib/ -v --with-doctest --doctest-extension=.rst -w examples/
 

The equivelent, without using pyrun, would be something like::

  cd pyrun-trunk
  PYTHONPATH=`pwd` nosetests -v --with-doctest --doctest-extension=.rst -w examples
