BPP (Bad Penguin Package) is a format that defines a not-so-new way of packaging software. BPP packages can be installed, removed, updated, restore, etc. You can also recreate a package from the file on your own filesystem, and if you carefully follow the documentation you can automate the process of mantaining packages. The BPP system provide all the tools to automatically download, compile, and install software in source code from the Internet diretly on your PC and assemble it into a package that can be re-distributed.
Sencap is a simple ENCAP software manager. Encapping is a method of installing software from source tarballs into private trees (bin, lib, man, share) and symlinking them to the system tree (e.g. /usr/local). Uninstallation of encapped software is quick, reliable and easy. Encapping is best used to augment the default package manager, not to replace it.
Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.
