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.
Payload Delivery Vehicle (PDV) is a program that builds an executable that contains a complete package (e.g. and RPM, System V package or tar file) and the commands required to install it. When the executable is run it will extract the payload (the package) and then execute another command (such as rpm -i, pkgadd -d etc.). The big advantage to this is that a developer can hand a user a single file to be executed - the end user does not need to know how to extract the package or get it installed.
Loki Setup is a graphical installer for Unix applications. It features descriptions of the package to install in XML, a GTK interface that can be dynamically redefined by the user with Glade, raw and ncurses console interfaces, and the automatic generation of uninstall scripts. It has been successfully used on many Linux and UNIX platforms. It includes tools for uninstalling, patching, and recovering installations. It operates independently from any package managers.
The RPM Package Manager (RPM) is a powerful command line driven package management system capable of installing, uninstalling, verifying, querying, and updating software packages. Each software package consists of an archive of files along with information about the package like its version, a description, etc. It also includes the RPM C library and header files. These development files will simplify the process of writing programs which manipulate RPM packages and databases and are intended to make it easier to create graphical package managers or any other tools that need an intimate knowledge of RPM packages in order to function.
epkg is a package manager which uses the Encap Package Management System, a method for flexibly handling installation and management of third-party software on a Unix system. Encap places each package in its own subdirectory, then automatically manages symlinks to their appropriate places in /usr/local. The Encap package format includes features like postinstall scripts and prerequisite checking. Other features include builtin tar/gzip extraction, optional builtin FTP and HTTP support, transaction logging, and the ability to automatically upgrade a package to the latest version.
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.
Purp is an acronym for Pugo-RPM, and it's a tool for managing RPM-packages. Purp uses the ncurses-library which means that it's textbased, and therefore can be used on most kinds of terminals. Purp provides a fast and efficient way to navigate, install, upgrade, and uninstall RPM-packages on ordinary text-terminal devices.
