# script to copy update complete projects with the packages meta data from obs to obs
# - uses "osc ci" to update target, so it generates a version history in the target obs for the packages
# - packages in the target with are not in the source will not be touched
# - if the list contains packages, which are not in the source, they are ignored
# - devel project/person userid are ignored
# - files with name "ready" are ignored
# - not copied or nor created are project wide data/meta data like build repos
#
# example: > osc -A api.opensuse.org ls Base:build | obs_project_update api.opensuse.org openSUSE:Factory api.d-atasoft.com openSUSE:Factory
