title: post commit hook to update a file under version
body: <p>I have made a file called version.ini that is under version control (/trunk/version.ini) 
  i now wanted to make a post commit hook to update that file with the latest version.
  But i dont know what command can do that. I know i have this params:</p>
  
  <pre><code>#!/bin/sh
  
  REPOS = "$1"
  REV = "$2" 
  </code></pre>
  
  <p>But how can i replace the content of that file without making a new revision ? and still have those changes in my repo ?</p>
  
  <p>UPDATE:
  Since maybe i havent been clear i will try a more detailed explination:
  Lets say i have this repo: /svn/repos/project/trunk/ and in it i have a file called version.ini that is under version control. What i want to do is that on every commit update that file to the new revision. Lets say that the current revision is 263 i want that file to have 263 writen in it. 
  And to respond to an answer bellow you cant use keywords since they only work if i update that file and i dont want to do it.</p>
  
  <p>Hope i made sense, and thanks for any help given.
  Cheers</p>
