# Packages installed:
# gcc; for compiling python extensions distributed with python packages like mysql-client
# git; for pulling requirements from GitHub.
# language-pack-en locales; ubuntu locale support so that system utilities have a consistent language and time zone.
# libmysqlclient-dev; to install header files needed to use native C implementation for MySQL-python for performance gains.
# libssl-dev; # mysqlclient wont install without this.
# pkg-config is now required for libmysqlclient-dev and its python dependencies
# python3-dev; to install header files for python extensions; much wheel-building depends on this
# python3-pip; install pip to install application requirements.txt files
# python; ubuntu doesnt ship with python, so this is the python we will use to run the application
# If you add a package here please include a comment above describing what it is used for
