# Dynamic Config Section #
# Set Python path in lieu of static settings of
# WSGIPythonPath in web server config.
# In embedded mode this file will be loaded and executed on each request.
# Dynamic config will marginally add to application startup time.
# Note: that to flush application code changes in embedded mode
#   all of the web server processes must be restarted:
#     e.g. service apache2 restart
# In daemon mode changes to this file are loaded and executed once
# into each daemon process. Since code is cached until modified.
