svn ignore for multiple folder / directories

I was struggling with the svn:ignore property to specify multiple folders. This is how I solved it:

set the environment variable EDITOR. I'm using ultra edit:
>set EDITOR="C:\Program Files\UltraEdit\uedit32.exe" (note the quotes)

Type in (note the period at the end, indicating the current folder is the target)
>svn propedit svn:ignore .

This will open the editor, UltraEdit in my case.
Enter the folder names separated on each line
Save and exit the editor.

That's it. Use svn status to see if indeed the folders are ignored.
