I do this for some of my own libraries (because I want the method to be 
RDoc'd as an attribute, but need to do something custom when setting), 
but be forewarned that this will cause Ruby to throw a warning about 
redefining the foo= method:

# The Dir instance or path to the directory to watch.
attr_accessor :directory
def directory=( dir ) #:nodoc:
    @directory = dir.is_a?(Dir) ? dir : Dir.new( dir )
end
