-
-Script to manage SQS queues. Can list or delete queues.
-
-Uses boto, so relies on correctly set up AWS access keys and tokens.
-
-In principle use this script to dump details of all queues in a gievn environment, and then
-manipulate the resultant CSV file so that it contains the queues you want to delete.
-
-Very hands on. Starter for a more automagic process.
-
-Usage:
-    scripts/delete_sqs_queues.py <action>
-
-    options are:
-    - list: dumps queue details to local file queues.csv in current directory.
-    - delete: delete queues from local file queues.csv in current directory.
