Hi all,
	I'm developing a rails web app here at work and I keep running into
a common thing in terms of setting instance variables with the property of a
form's parameter value. Basically I want the variable to take the
parameter's value if it exists, and to otherwise use a reasonable default.

I keep writing code like this:
    if @params["limit"]
      @limit = @params["limit"]
    else
      @limit = 50
    end

    if @params["chain"]
      chain = @params["chain"]
    else
      chain = 1
    end

Can someone please point me to a simpler, more succinct "ruby" way of doing
this?

Thanks,
Chris
