Cloud User Shell (cush) is a multi-call executable bringing RESTful cloud control to the command line, combining many useful cloud computing utilities into a single executable. It follows the Unix philosophy of writing components that work together, do one thing and do it well, and communicate over text (HTTP) streams. It is also RESTful, clearly delineating the 3 sides of the REST Triangle: verbs (e.g. GET), nouns (e.g. http://samj.net/), and content types (e.g. text/html).
Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
