+    2016/10/27
+        - Create folders for new files created by a patch if needed
+        - Adding support for patches created with git diff on non svn platforms
+          (git diff on OSX creates source/target as /dev/null
+          for new/deleted files)
+

         - Write to stdout instead of using warning() for messages
