   Copyright (c) 2010, Arc Worldwide

   Two configuation variables are listed below and should be set based on the 
   specifics of your deployment:

   * econduit_base_path - URL path to the root of the eConduit Pipeline directory, 
                          including the top-level "econduit" directory.
   * econduit_exclude_names - list of filenames for default pages, such as index.html

   NOTE: This is a pre-release version that includes code for logging debugging 
         messages to the Javascript console.  These will be removed in the final
         production release.
