  --env                      Use shell ENVIRONMENT variables to fill the
                             $placeholders in the template.

  --pickle <file>            Use a variables from a dictionary stored in Python
                             pickle file to fill $placeholders in the template.

                             '%(scriptName)s --pickle -'

Description
-----------

This interface allows you to execute a Cheetah template from the command line
and collect the output.  It can prepend the shell ENVIRONMENT or a pickled
Python dictionary to the template's $placeholder searchList, overriding the
defaults for the $placeholders.
