Versium is a simple abstract API over several storage solutions, all of which provide access to a collection of versioned documents or "nodes". Nodes carry Lua byte-string data as their payload, but no assumptions are made about its content. The client interacts with versium through the "versium" module, which then delegates most of the work to a specific storage implementation (specified at the initialization time). Two storage implementations are included with this rock: "simple" which stores nodes and their histories on the file system and "virtual" which stores them in memory. Other implementations (e.g., using subversion or a database) are provided as separate rocks.
