title: How to implement auto compile like java Servlet , PHP CMS template?
body: <p>I want to implement a small PHP template engine like smarty which would allow me to write my own php tag(if,for ..)</p>
  
  <p>And now ,my problem is how to compile automatic when the template file was modified? </p>
  
  <p>For example: Servlet . When we modified the servlet and waited for seconds ,the eclipse would tell you that the modified servlet class was recompiled ! </p>
  
  <p>Any help would be great!</p>
