Install

sudo gem install zookeeper

Usage

Connect to a server:

require 'rubygems'
require 'zookeeper'
z = Zookeeper.new("localhost:2181")
z.get_children(:path => "/")

Idioms

The following methods are initially supported:
  get
  set
  get_children
  stat
  create
  delete
  get_acl
  set_acl

All support async callbacks.  get, get_children and stat support both
watchers and callbacks.

Calls take a dictionary of parameters.  With the exception of set_acl, the
only required parameter is :path.  Each call returns a dictionary with at
minimum two keys :req_id and :rc.
