+@descr:  little script that finds subdomains of a domain specified
+         as a command line argument
+@author: Evan J Johnson

+@bugs:
+It doesn't work amazingly. It works okay. I had the idea that this might work...
+but I think it needs more work. It will only find subdomains that have been indexed by
