Abstract
The paper describes a project for distributing application
software in the large worldwide High Energy Physics (HEP)
community. Hundreds of packages are maintained centrally and users
can access them directly through the network. Workstation
administrators can optimise access performance and reliability by
specifying in their installation scripts the packages to be copied
locally or accessed remotely. Product maintainers have a set of
tools to generate their packages from the sources, while site
administrators can replicate (part of) the central file-base
manually or automatically. The generation takes place in different
physical network domains. Replication on remote domains implies
only propagating changes of the repository.
