+# Short-Description: An object/document-oriented database
+# Description: MongoDB is a high-performance, open source, schema-free
+# document-oriented data store that's easy to deploy, manage
+# and use. It's network accessible, written in C++ and offers
+# the following features:
+#
+# * Collection oriented storage - easy storage of object-
+# style data
+# * Full index support, including on inner objects
+# * Query profiling
+# * Replication and fail-over support
+# * Efficient storage of binary data including large
+# objects (e.g. videos)
+# * Auto-sharding for cloud-level scalability (Q209)
+#
+# High performance, scalability, and reasonable depth of
+# functionality are the goals for the project.
