title: Understand what is KBuild
body: <p>I'm a newbie to Linux kernel.</p>
  
  <p>I'm trying to understand the idea, high level what is <a href="http://svn.netlabs.org/kbuild/" rel="nofollow noreferrer">kbuild</a>.</p>
  
  <p>When I compile kernel I call <em>make</em>, which is on Linux machine will GNU make.</p>
  
  <p>So what is KBuild? Is it a set of makefiles which are used by including in kernel makefiles? 
  Where <a href="http://svn.netlabs.org/kbuild/wiki/kmk%20Quick%20Reference" rel="nofollow noreferrer">kmk</a> is used?</p>
  
  <p>Reference will be helpful.</p>
  
  <p>Thanks</p>
