cdpack is a small utility for creating ISO 9660 images for a multi-CD/DVD binary package collection. The utility creates ISO 9660 images for all the binary packages in a specified directory. A choice of two algorithms is available for how the packages are grouped. The "no duplication" algorithm arranges the packages so any package on CD/DVD number `n' will have all of its dependencies on CD/DVD numbers 1 through `n'. The "no inter-CD/DVD depends" algorithm will place certain packages on more than one CD/DVD to ensure that each CD/DVD is self contained (all package dependencies are satisfied within the single CD/DVD). The cddist utility in this package is used for creating an archive set of distfiles.
