Slackpack is a package manager for Slackware Linux. It has a friendly GUI environment and can install packages, list installed packages, remove Slackware Linux packages (.tgz or .txz), and convert to .tgz format from .deb or .rpm. It can download Slackware Linux packages from package repositories, and can create .tgz packages from an application’s source code.
Simple Package Manager (SPM) is intended to operate in a way similar to existing package managers (apt, dpkg, Pacman, etc.). Instead of supporting a centralized package repository, SPM allows remote packages to be downloaded and installed automatically, given their URL. This allows a developer to package and distribute software via a package management system without having to worry about the many different formats and Linux distribution repositories.
Upmf is a source-based package manager written almost completely in Scheme. The user is able to search, build, and remove packages. Since Scheme through GUILE is very extensible, the user can customize the procedures, or even exchange them with his own, if wanted. Packages are stored in their own self-contained directories and are incorporated into the filesystem with help of GNU Stow.
