BZip2/OSS-QM is the OSS-QM project's branch of bzip2, which contains a lot of fixes not yet in the original upstream. The primary goal is to provide QM'ed/fixed versions of upstream releases, so they can be built and used without additional patches, especially in sysrooted crosscompiling environments.
Depot is a software management tool providing a simple, yet flexible, mechanism for maintaining third party and locally developed software in large heterogeneous computing environments. Depot integrates separately maintained software packages, known as collections, into a common directory hierarchy consisting of a union of all the collections. This common directory is defined as the software environment. A set of configuration options manages interactions and intersections between collections in the environment. Depot facilitates the introduction, update, and removal of collections in a software environment. Custom environments and complete test environments can be easily created for individual machines or for sets of machines. Collections with unexpected problems can be replaced with previous versions or simply removed. Individual collections or files can be moved from remote filesystems to the local disks of workstations without the worry that the files may become stale. All this is achieved with minimal wasted disk space and administrative overhead.
The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
Fileprune will delete files from a collection, targeting a given distribution of the file timestamps within time as well as size, number, and age constraints. Its main purpose is to keep a set of periodically-created backup files to a manageable size while still providing reasonable access to older versions. The algorithm used for pruning is based on an exponential, Gaussian (normal), or Fibonacci distribution, and supports collections of files stored at irregular intervals.
