#  build-deb-aomp.sh:  Using debhelper and alien, build the aomp debian and rpm packages
#                      This script is tested on amd64 and ppc64le linux architectures. 
#                      This script needs packages: debuitils,devscripts,cli-common-dev,alien
#                      A complete build of aomp in /usr/lib/aomp_$AOMP_VERSION_STRING
#                      is required before running this script.
#                      You must also have sudo access to build the debs.
#                      You will be prompted for your password for sudo.
