title: When using Mercurial HG, how to just get the latest code?
body: <p>I am new to Mercurial HG. My friends created a repo and I am going to use it. 
  I installed TortoiseHG and trying to get the latest code. I found that when using Clone operation, it will pull all code to my local, including the histories (Am I right?). This is not needed for me. I just wanna get the latest code. Is there an operation for this?</p>
