Use parameters in Hudson in configuration

I am 开发者_运维技巧looking into the "parameterized build"-feature of Hudson CI.

I would like to make this a parametrized build and then use one of the parameters as part of the svn URL.

e.g I would like to configure the svn URL as http:/oursvnserver/repos/branches/$PARAMETER

is this doable, or are there smarter ways to do this?

That's how I do it. Except, I use it for the revision. Go for it.
