title: What does "Modify files with subversion/git" mean?
body: <pre><code>% rails
  ...
  General Options:
  ...
  -c, --svn                        Modify files with subversion. (Note: svn must be in path)
  -g, --git                        Modify files with git. (Note: git must be in path)
  </code></pre>
  
  <p>What do these "Modify files" options do for me?</p>
  
  <p>Edit: It is unclear to me what using one (or both?) of these options actually does. As in, how do they alter workflow? What svn/git commands would I then not be issuing myself, or possibly what type of more esoteric commands will I now end up having to issue? Fundamentally, where are the docs on this feature?</p>
