> Added a '-force' option to the 'bin/nutch crawl' command line. With this 
> option, one can crawl and recrawl in the following manner:
> {code}
> bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5
> bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5 -force
> {code}
> This option can be used for the first crawl too:
> {code}
> bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5 -force
> bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5 -force
> {code}
> If one tries to crawl without the -force option when the crawl directory 
> already exists, he/she finds a small warning along with the error message:
> {code}
> # bin/nutch crawl urls -dir crawl -depth 2 -topN 10 -threads 5
> Exception in thread "main" java.lang.RuntimeException: crawl already
> exists. Add -force option to recrawl.
