Ravenports is an integrated system designed to build packages of complex software on all UNIX-like platforms. It is considered “universal” because Ravenports is not anchored to any single operating system; once the build procedure for a particular software is created (a.k.a “port”), that software is then available for all supported platforms. The simplest use case is to access the freely available prebuilt package repository for each supported platforms. More complex usage involves customizing builds to create private package repositories for specialized use. The product packages and repositories are manipulated with a package manager.
