I decided to spider my web pages, using the the method given
in the "INSTALL - Swish-e Installation Instructions":

     # Example for spidering
     # Use the "spider.pl" program included with Swish-e
     IndexDir spider.pl

     # Define what site to index
     SwishProgParameters default http://...

When I ran the program, I saw the following messages:

   rdm@flora02 $ swish-e -S prog -c swish2.conf
   Indexing Data Source: "External-Program"
   Indexing "spider.pl"
   External Program found: /u/gl/rdm/local/lib/swish-e/spider.pl
   No SWISH filters found
   /u/gl/rdm/local/lib/swish-e/spider.pl: Reading parameters from 
'default'
   RobotRules: Unexpected line: Sutton
   ...

Clearly, some program found "Sutton" somewhere and wasn't happy,
but this isn't enough information to allow the user to debug
anything.  Could we have a more comprehensive error message?
