buildone or more packages. These resources include source archives,
patch files,spec files, etc. The project defines the build
architectures and thegeneral settings. Package The packages are the

Current Release All packages are in the release project and
theupdate project, e.g. openSUSE:12.1 andopenSUSE:12.1:Update. Each
package update must be reviewed bythe maintenance team and then be
submittedto the update project. In general, every update has to be
tracked bya bugzilla entry. 17. Maintenance ProcessopenSUSE
