title: SVN Checkout a single directory
body: <p>Here is my dilemma:</p>
  
  <p>I want to checkout a single directory (let's call it A) from SVN, but be able to do and svn up A from the parent directory on the computer is checked out on.</p>
  
  <p>i.g.  I am on in ~/coolstuff  I want do do a checkout of A and put it in ~/coolstuff and when I am in ~/coolstuff I want to issue svn up and have it update A.</p>
  
  <p>Here is a trick to do this in a basic scenario:
    In SVN A's parent directory is Z.  I do an SVN checkout of Z in ~/coolstuff.  I then mv ~/coolstuff/Z/.svn to ~/coolstuff.  Walla I can do a svn up and it works and it will pull down A inside of ~/coolstuff.</p>
  
  <p>My scenario:
   I do the same thing above, except the problem is that Z not only has the child A, but it also has the child B.  So a svn up in ~/coolstuff will pull down A and B.  But I don't want B to be pulled down.</p>
  
  <p>Here is the solution:
   I edit ~/coolstuff/.svn/entries and removed the reference to B.  Now svn doesn't see B, only A.</p>
  
  <p>The solution above still initial pulls down A when I do the first checkout, I don't want to do this.  It also seems very hack-ish.  Is there a better/cleaner way to do this, and hopefully not have to pull down "B" at all?</p>
