title: How to access the tag name in svn pre-commit hook
body: <p>I have a list of tags that cannot be changed and was wanting to implement a pre-commit hook that will check my list to make sure that none of the files being changed are in any of the immutable tags.</p>
  
  <p>It seems I only have access to the revision number and path to the repo in the <code>pre-commit</code> script. How can I check against my tag list to see if any files being committed are in one of the listed tags? Basically I need to make sure that any commits of files that have a <code>tags/TagInList/</code> prefix will be denied, where I would run something like:</p>
  
  <pre><code> grep 'tagOnCommitFile' /path/to/tagListFile
  </code></pre>
