title: When do we use ANTLR
body: <p>Can anyone please guide me the purpose of using ANTLR dlls in a ASP.Net, C# project.</p>
  
  <p>I just noticed <em>antlr.runtime</em>, <em>Antlr3.Runtime</em>, <em>Antlr3.Utlility</em> assemblies being referenced in some project.</p>
  
  <p>Will be great if can cite some real world examples or any link to a web page will be useful.</p>
