#Current key is always the most current version of the document. Everytime it gets modified, we increase the count of versions and save current couchbase version of document #as a version with current_version - 1 appended.

#So:

#create_doc
#mydoc = { "txt" => "my first text" }

#replace_doc
#mydoc::version = 2
#mydoc::version::1 = { "txt" => "my_first_text", "auto_version" => 1, "auto_version_stamp" => "6/28/2012 20:35" }
