This tool provides a sysadmin-friendly command line interface to Amazon Glacier, turning Glacier into an easy-to-use storage backend. It automates tasks which would otherwise require a number of separate steps (job submission, polling for job completion and retrieving the results of jobs). It provides integration with git-annex, making Glacier even more useful. glacier-cli uses Amazon Glacier's archive description field to keep friendly archive names, although you can also address archives directly by using their IDs. It keeps a local cache of archive IDs and their corresponding names, as well as housekeeping data to keep the cache up-to-date. This will save you time because you won't have to wait spend hours retrieving inventories all the time, and will save you mental effort because you won't have to keep track of the obtuse archive IDs yourself.
