#	Mnemonic:	run_all.ksh (bash compatable)
#	Abstract:	This script will drive all of the application tests and ensure
#				that the environment is set up as follows:
#
#					Any deb packages which exist in BUILD_PATH are 'installed'
#					into a /tmp directory so that application builds can reference
#					them.
#
#					References are set up to find the NNG library files in the
#					BUILD_PATH directory.
#
#				The BUILD_PATH environment variable should be set, and if not the
#				two directories ../.build and ../build are checked for and used.
#				If the var is not set, and nether of these directories exists,
#				the tests will not be executed.
#
#				At the moment, it assumes a deb based system for tests.
