stableUpdate is an autoupdate tool for creating, detecting, downloading, installing, and removing service packs for JAR-based Java applications. Generated updates are transferred in archives, upgrading between subsequent versions. An update contains changed single files and changed parts of JAR and ZIP files. It supports mirrors, release notes, and uninstallation of updates.
Stash is a package manager for non-root users. It makes it easier for you to install, track, and maintain packages and modules in your home directory. It does this by detecting the type of package or module you are installing and passing all the correct command line arguments to the relevant configure scripts and/or makefiles. It is extensible via custom packages, and tracks both architecture dependent and independent packages in separate directories so that they can be shared across systems. Package tracking uses symlinks in a manner similar to GNU stow. It supports autoconf, Perl and Python modules, imake (xmkmf), PMK, and many custom packages.
A simple and trivial to use utility for keeping various 3rd party application packages installed on multiple machines. It leaves flexibility for making packages local to a host or remotely served from a central server. It is not the same sort of tool as RPM; rather it serves a related but different purpose. In particular, unlike most package systems, it can run independently of your main system (RPM, pkgadd, etc) and lets you install multiple versions of an appplication at the same time.
Sysinit is a system-initialization scheme for use with Linux and a daemon-management scheme for use with runit or daemontools. It provides a common interface to all functionality, and uses envdirs instead of sourced shell scripts or custom configuration files. It does error handling, handles dependencies gracefully and simply, and handles runlevels.
tkxinput contains Xi, a library that adds Xinput management capabilities to the Tk toolkit, and a utility named calibrate that can be used to test various aspects of the Xinput configuration of an X server. calibrate can be used, as its name implies, as a touchscreen calibration facility.
toast is a simple package manager for Unix. It automatically locates and downloads source code, determines how to compile it, installs each package in its own directory tree, and makes the resulting binaries available through an encap/GNU stow-like symlink tree. It also supports binary packages. It is often used to install and manage software in a non-root user's home directory.
