title: What does the Subversion status symbol "~" mean?
body: <p>I am getting a tilde symbol when I do an <code>svn status</code>.</p>
  <p>Here is the output of the project after editing it in XCode.</p>
  <pre><code>svn status
  M      build/Currency_Converter.build/Currency_Converter.pbxindex/imports.pbxbtree
  M      build/Currency_Converter.build/Currency_Converter.pbxindex/pbxindex.header
  M      build/Currency_Converter.build/Currency_Converter.pbxindex/symbols0.pbxsymbols
  ~      build/Currency_Converter.build/Currency_Converter.pbxindex/strings.pbxstrings
  M      main.m
  //more changed files
  </code></pre>
  <p>Any idea what that means? Can't seem to find it on google or any of the svn cheat sheets.</p>
  <p>Interestingly, I only edited main.m, but there are lots of modified files. I don't know why that would be. Anyone have any tips for working with SVN and XCode? Should I only be putting my source files under version control?</p>
  <p><strong>Edit:</strong> Caused by a file that was already under version control being replaced by a file of another type. In this case, strings.pbxstrings used to be a file and now became a directory. Moral of the story is don't put your build folder into version control.</p>
