# Short-Description: Apache CouchDB, a RESTful document oriented database
# Description:       Apache CouchDB is a distributed, fault-tolerant and schema-free
#                    document-oriented database accessible via a RESTful HTTP/JSON API. Among other
#                    features, it provides robust, incremental replication with bi-directional
#                    conflict detection and resolution, and is queryable and indexable using a
#                    table-oriented view engine with JavaScript acting as the default view
#                    definition language.
