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

# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# 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.

	# Provides: mongodb

	# 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.
