# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
#   the WebSocket protocol implementation in the cramp gem does not work
#   well with Chrome's (newer) WebSocket implementation.

# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby
