# File: dependencies.sh

# Purpose is to install the various dependencies.
# It is assumed that your OS has python 2.7 as the default python.

# With the change from jesse to stretch, the libmysqlclient-dev
# package was chanaged to default-libmysqlclient-dev.

# default-libmysqlclient-dev    #stretch
# libmysqlclient-dev      # jesse

# RE DEBIAN_FRONTEND: see
# https://serverfault.com/questions/227190/how-do-i-ask-apt-get-to-skip-any-interactive-post-install-configuration-steps
# May need to add the -q option. (see man apt-get)
