title: Available Build Tools (make, etc)?
body: <p>There's a lot of questions on here regarding various niche build needs (.NET, continuous integration, etc) but, of course, my niche need is different.</p>
  
  <p>Rather than asking a very specific question right now, I'd like a survey of available build tools (such as make, ant, etc) so I can ask a follow up question more intelligently if needed.</p>
  
  <p>In your answer, please include:</p>
  
  <ul>
  <li><strong>ONE</strong> build tool</li>
  <li>Link to the main page about that tool</li>
  <li>If you know some pros and cons (ie, runs on windows with cygwin, or .NET specific, etc) then list some (not required - the name and link are required)</li>
  </ul>
  
  <p>If your build tool is already in an answer, comment on it adding pros/cons/limitations/experiences.  Feel free to add as many answers as you like as long as they don't already exist - but don't put several build tools into one answer.</p>
  
  <p>Please be aware that if you duplicate answers you may be downvoted - add additional information about a given build in the comments.  Ideally these comments will be incorporated into the answer over time.</p>
