#
#	Mnemonic:	run_all_tests.ksh
#	Abstract:	This should allow one stop shopping to run all tests as
#				follows some are explicit, some are implied (e.g. if nng
#				doesn't build correctly RMr won't build):
#
#				- complete build of RMr code and generation of a .deb with 
#				  expected content
#
#				- complete build of Nanomsg and NNG
#
#				- complete execution of the unit test script
#
#				Assumptions:
#					- code is cloned, and the PWD is the top level repo directory
#					- running in a container such that 'make install' can be
#					  executed to install RMr and NNG/Nano libraires in /usr/local
#					- needed utilities (cmake, make, gcc, ksh) are installed
