The import option specifies Python modules (not Spyce modules)
that should be loaded (i.e. imported) at server startup. This can be useful to
perform initialization at server startup. Using the pool module is prefered for storing
long-lived values. The string for this option is a comma-separated list of
Python module names. In CGI-mode, the Spyce engine is restarted on each
request, so these modules will be loaded on each request. For other
configurations, the import is performed once. To use this module, you will
still need to import the module in your Spyce modules or Spyce files, but it
will be taken from the Python module cache.
