  module MultiClient

    # is lazily instanciated by calling the matching FlexmlsApi.symbol_name method on the

    # method.
    # Parameters
    #  @sym - the unique symbol identifier for a client configuration.
    #  &block - a block of code to run with the specified client enabled, after which the original
    #    client setting will be reenabled
