Recrawl script

[Chris Stephens]

How does the depth option work on the 0.8 recrawl script that is on 
http://wiki.apache.org/nutch/IntranetRecrawl .  I just want to re-index 
all of the pages currently in the db and not index any new pages these 
pages might link to.  Should I use a 0 for this?  It seems like the 
fetcher never runs when I do 0, and if I do anything above zero it 
starts indexing at a further depth then what is currently in my crawl 
db, which is further then I desire.
