rconftool is a reimplementation of Sam Varshavchik's sysconftool in Ruby. Its purpose is to keep configuration files "fresh" when upgrading an application from one version to another, ensuring that all necessary settings are present and that obsolete ones are removed. To use it, application writers need to distribute their config files marked up with some simple metadata in comments, and arrange for the "make install" or "make install-configure" target to invoke rconftool. rconftool can be called as a library function or from the command line. It can also install groups of files recursively from one directory tree into another.
PiSi is a modern package manager for UNIX systems. It has been designed to meet the requirements of the Pardus Linux distribution, and it is not derived from any other package manager. It is efficient and small. Package sources are written in XML and Python. Fast database access is implemented with Berkeley DB. It integrates both low-level and high-level package operations. Sources can be maintained easily through a version control system as original sources do not have to be copied. It uses a framework approach to build applications and tools upon. It has both a comprehensive CLI and a user-friendly Qt-based GUI.
pkg_db.pl generates a pretty-printed HTML list and statistics of packages installed via NetBSD pkgsrc. It creates 3 HTML files: one index, containing a list of all installed packages with short descriptions, one with the detailed description of the package, and one with a list of installed files. It requires pkg_info.
logGen is a command-line utility for detecting filesystem changes after a preference change or package installation. This is primarily useful when creating your own .pkg files so you know what you need to package. This package is only compatible with OS X 10.3 and above due to some perl modules that are missing in earlier versions. If you need to run it on OS X 10.2, you'll need to install the necessary perl modules manually.
cerbeRun is a software runner. The applications are stored inside a .tar (version 0.3 will use the ISO9660 format) file renamed with the extension .run. cerbeRun's format allows you to switch between different architectures using an .xml file, in which are specified different rules for different archictures. This is all done in user space without root access.
