### BEGIN INIT INFO
# Provides: mongodb
# Required-Start: $network $local_fs $remote_fs

# Should-Start: $named

# 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.
