Paludis is a package manager for Gentoo (and derived distributions) and Exherbo. It consists of a core library and a number of console-based clients. Package formats supported include Gentoo ebuilds and kdebuilds (as defined by the Package Manager Specification), the Exherbo exheres-0 format, and various miscellaneous utility pseudo-formats for managing accounts, unwritten and unavailable packages, and packages for which no package exists.
makeself is a small shell script that generates a self-extractable compressed TAR archive from a directory. The resulting file appears as a shell script, and can be launched as is. The archive will then uncompress itself to a temporary directory and an arbitrary command will be executed (for example, an installation script). This is pretty similar to archives generated with WinZip Self-Extractor in the Windows world.
autopackage allows developers to produce "install anywhere" packages for 3rd party Linux software. The resulting packages support both graphical and terminal frontends, support dependency checking and resolution, and use deep desktop integration. Additionally, tools to enhance the packaged software such as binreloc and relaytool are provided. By providing an autopackage, developers can ensure their users always have an easy way of installing the latest release of their software.
Slackpkg is an automated package-management tool for Slackware Linux. It can do tasks such as automatic downloading and installing or upgrading, browse the MANIFEST.gz (Slackware package-contents guide), and more. Dependencies are not automatically handled. It is not a replacement for pkgtool, but a valuable add-on.
DSWIM is a powerful informational tool for Debian's packaging system. Designed with an integrated approach it combines the functionality found in several other programs and scripts. This provides users with a centralized approach for querying the installation, allowing programmers the liberty of writing smaller and simpler code.
Releaser is a set of scripts to automate and manage the tasks related to software package releases. It is designed to be modular and to make it easy to both select a particular set of actions associated with releases of a particular project (such as changelog generation, uploading of tarballs, posting announcements to mailing lists), and create new actions that integrate seamlessly into the process. Its status is still somewhat experimental, but the most basic functionality is there.
