title: Eclipse: On Save execute a program
body: <p>I have recently come across the <a href="http://lesscss.org/" rel="noreferrer">LESS Leaner CSS</a> a template engine for CSS based on ruby. The idea sounded neat, but in practice we need to compile the program to get CSS. This is cumbersome as we make too many changes while working on CSS and for every edit we don't want to compile. </p>
  
  <p>In Eclipse, there are "Save-Actions" but it handles only formatting changes.</p>
  
  <p>Is there a way on saving the file in Eclipse, to call or trigger the compilation?</p>
  
  <p>Its easy to do this in Vi or Emacs.</p>
