Comment 2 for bug 600962

Unfortunately, I've discovered that restish doesn't support PATCH. Due to the way restish uses WebOb, it does not appear possible to hack support for that in. I'll submit bug reports to both upstreams and continue to implement PUT. This means that you'll have to change the entire state of the mailing list resource every time you want to change more than one attribute.

However, I also think I can make it so you can change just one attribute at a time. This will be less efficient when you want to set multiple values, but it should still give you something workable for now.
