• SVN ignore tips:
  1. cd to the parent folder of the folder you want to ignore.
  2. svn propedit svn:ingore .
  3. This will pop upon whatever editor is configured. Enter the files or folders you wish to ignore each on their own line.
  4. Exit the editor.
  5. Commit the change.
  6. If it gives you guff (sometimes it does) update the current folder and try again.
