title: Web mining or scraping or crawling? What tool/library should I use?
body: <p>I want to crawl and save some webpages as HTML. Say, crawl into hundreds popular websites and simply save their frontpages and the "About" pages.</p>
  
  <p>I've looked into many questions, but didn't find an answer to this from either web crawling or web scraping questions.</p>
  
  <p>What library or tool should I use to build the solution? Or is there even some existing tools that can handle this?</p>
