# Usage: $ ./deploy_nepi_engine_3rd_party.sh
#
# Only need to deploy and build these once on new systems
#
# This script copies the complete nepi_engine 3rd_party source code to proper filesystem locations on target
# hardware in preparation for building nepi-engine from source. 
#
# It can be run from a development host or directly on the target hardware as described in this
# repository's README
#
# The script requires the following environment variable be set
#    NEPI_REMOTE_SETUP: Indicates whether running from development host or directly on target 
#                      (1 = Dev. Host, 0 = From Target)
# In the case that NEPI_REMOTE_SETUP == 1, some further environment variables must be set
#    NEPI_TARGET_IP: Target IP address/hostname
#    NEPI_TARGET_USERNAME: Target username
#    NEPI_SSH_KEY: Private SSH key for SSH/Rsync to target (as applicable)
#    NEPI_TARGET_SRC_DIR: Directory to deploy source code to (except _nepi_rui_, which must be located 
#                         at _/opt/nepi/nepi_rui_ as described in that submodule's README)
