this has been ruthlessly stolen from Thor/runner.rb - please do not hunt me for that :)

def find_config_file(skip_lookup = false)
  # Finds docker-sync.yml by traversing from your current directory down to the root
  # directory of your system. If at any time we find a docker-sync.yml file, we stop.
  #
  #
  # ==== Example
  #
  # If we start at /Users/wycats/dev/thor ...
  #
  # 1. /Users/wycats/dev/thor
  # 2. /Users/wycats/dev
  # 3. /Users/wycats <-- we find a docker-sync.yml here, so we stop
  #
  # Suppose we start at c:\Documents and Settings\james\dev\docker-sync ...
  #
  # 1. c:\Documents and Settings\james\dev\docker-sync.yml
  # 2. c:\Documents and Settings\james\dev
  # 3. c:\Documents and Settings\james
  # 4. c:\Documents and Settings
  # 5. c:\ <-- no docker-sync.yml found!

Where to look for docker-sync.yml files.
