title: How to install w3c validator on ubuntu 10.04
body: <p>I have configured Unicorn locally on my machine, I can also able to run it on console. What I want to know is how to install w3c validation tools like markup validator, css validator, mobileok-check validator and w3c-validator on ubuntu. And also tell me how to configure unicorn for locally installed validators. Official sites are little difficult to understand so please suggest me some other site.</p>
  
  <p>note 1: People from W3C says "Unicorn can only get results from other validators through HTTP, which means I have to install the other validators on a web server (which can be installed locally). I can able to use Unicorn fully locally."</p>
  
  <p>note 2: I followed this link(http://thecodetrain.co.uk/2009/02/running-the-w3c-css-validator-locally-from-the-command-line/) and have already installed css validator it works fine</p>
