title: TortoiseSVN client pre commit hook to check the contents of file being committed
body: <p>I want to write a pre commit hook in windows batch file which will check for specific string in the file being committed. If the string exists, the commit will fail. I have TortoiseSVN client installed. As it's tortoisesvn client, it does not have commands like 'svnlook' to fetch the list of files etc. I want that script to be executed for each and every file being committed/added.</p>
  
  <p>I am newbie to these hooks. Can anyone please guide me with this?</p>
