title: How to manage revision numbering in a SVN tag?
body: <p>I wonder how to deal with the RN (revision number) in my software project.
  The RN is placed in a separate header file and is shown in the about view and looks something like this: <code>v1.23.456</code></p>
  
  <p>Normally I crate a tag like this:</p>
  
  <p><strong>1. Create the tag by:</strong></p>
  
  <pre><code>svn copy http://myrepo/trunk http://myrepo/tags/1.23.456 -m"Tagged version 1.23.456"
  </code></pre>
  
  <p><strong>2. Check out the tag and edit the RN:</strong></p>
  
  <pre><code>svn co http://myrepo/tags/1.23.456
  gedit revisionNumber.h
  </code></pre>
  
  <p><strong>3. Check in the adapted RN:</strong></p>
  
  <pre><code>svn ci revisionNumber.h -m"Adadpted RN"
  </code></pre>
  
  <p>--> It is a bad workaround to edit a tag. But I don not know another way to manage the RN. So my question is: </p>
