Subject: [ruby-talk:15501] StringBuffer IO Class

Is there a built in or has anyone developed a string buffer stream class as
an IO object.  I would like to redirect standard out at certain times to
such a buffer.  If not, is there an alternative way to redirect stdout to a
regular string object?

Here is pseudocode for what I want to do - I'd be really appreciative if
anyone could help fill in the blanks with ruby code.

def foo
  # redirect stdout to a buffer (buff)

  # do some work that may result in writes to stdout

  # redirect stdout back to original stdout

  # write contents of buff to stdout
end
