title: Wget to download Wikipedia text
body: <p>This is what I want to do:
  Given an initial url (eg. <a href="http://en.wikipedia.org/wiki/Lists_of_scientists" rel="nofollow">http://en.wikipedia.org/wiki/Lists_of_scientists</a>), I want to visit all the links on that page (relevant links of course).
  Each link corresponds to another page containing several other links (eg. <a href="http://en.wikipedia.org/wiki/List_of_American_scientists" rel="nofollow">http://en.wikipedia.org/wiki/List_of_American_scientists</a>). I want to visit each such link so that I can extract xml information from them.
  Can this be done using wget? Someone suggested I should use Scrapy, however I am facing problem installing it.
  The hierarchy to crawl looks like this: List of Scientists->List of American Scientists->Bryan Hayes (And a lot more scientists).</p>
  
  <p>My target is to extract basic information from these wiki texts, like a person's name, organization, age, etc.</p>
  
  <p>PS: I am a NOOB with good understanding.</p>
