# 1. INSTALL MongoDB PACKAGES OR BINARIES

# 2019-02-02: Sugarizer with Node.js 10.x requires MongoDB 2.6+ so
# https://andyfelong.com/2017/08/mongodb-3-0-14-for-raspbian-stretch/ is
# being used on Raspbian, all I found! (Raspbian's apt pkg is MongoDB 2.4.14)
#
# mongodb_stretch_3_0_14_core.zip (20M) & mongodb_stretch_3_0_14_tools.zip (15M)
# were backed up from andyfelong.com to http://download.iiab.io/packages/
#
# CLARIF: mongodb_stretch_3_0_14_core.zip IS IN FACT 3.0.14 (core) BUT...
#         mongodb_stretch_3_0_14_tools.zip IS REALLY 3.0.15 (tools)
