message: Show how to use "lldb -P" to find the lldb.py.
  We had hard-coded the path in the docs but that got
  out of date - showing again that -P is the better
  way to do this.

  <b>LLDB.framework</b> to create your own stand-alone python programs, you will
  need to tell python where to look in order to find this module. This
  is done by setting the <b>PYTHONPATH</b> environment variable, adding
  - a path to the directory that contains the <b>lldb.py</b> python module. On
  - Mac OS X, this is contained inside the LLDB.framework, so you would do:
  + a path to the directory that contains the <b>lldb.py</b> python module. The
  + lldb driver program has an option to report the path to the lldb module.
  + You can use that to point to correct lldb.py:
  <p>For csh and tcsh:</p>
  - <p><code>% <b>setenv PYTHONPATH /Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Python</b></code></p>
  + <p><code>% <b>setenv PYTHONPATH `lldb -P`</b></p>
  <p>For sh and bash:
  - <p><code>% <b>export PYTHONPATH=/Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Python</b></code></p>
  + <p><code>% <b>export PYTHONPATH=`lldb -P`</b></p>
  <p> Alternately, you can append the LLDB Python directory to the <b>sys.path</b> list directly in
  your Python code before importing the lldb module.</p>
