#	Mnemonic:	ci_build.ksh
#	Abstract:	Script builds RMr, exececutes the unit and application based
#				tests, then generates packages. The packages are left in /tmp
#				unless -t target-dir is given on the command line. A YAML file
#				is created which can be used to find all of the packages which
#				were deposited in the target directory. In an environment which
#				is also capable of generating RPM ppackages, there should be
#				four packages: a run-time and development package for both
#				debian (.deb) and rh (rpm) based systems.
#
#				The intent of this script is for it to be executed as a part
#				of a docker image build process such that the resulting image
#				contains the RMr packages, and a YAML file which provides the
#				paths to the package(s) in the image.  Docker tools can then
#				be used to extract the packages and push them to some external
#				repository.
#
#				Assumptions:
#					We assume that this scirpt is executed at the 'root' of the
#				RMr repo (i.e. the directory which has a subdirectory ci).
