 for an application. Supports loading the records from queue.yaml.
 
 A queue has two required parameters and one optional one. The required
-parameters are 'name' (must be unique for an appid) and 'rate' (the
-rate at which jobs in the queue are run). There is an optional 'bucket_size'
-that will allow tokens to be 'saved up' and bucket_size. Rate and bucket_size rate are
-expressed as number/unit, with number being an int or a float, and unit being
-one of 's' (seconds), 'm' (minutes), 'h' (hours) or 'd' (days).
+parameters are 'name' (must be unique for an appid) and 'rate' (the rate

+'bucket_size' that will allow tokens to be 'saved up' (for more on the

-An example of the use of bucket_size rate: the free email quota is 2000/d, and the
-maximum you can send in a single minute is 11. So we can define a queue for

 the first 10 jobs submitted would be run immediately, then subsequent ones
