QML (Quantity Modeling Language) is a "thing"-based language for scientific and mathematical data modeling. Each "thing" is a quantity which may be associated with either a structure or physical phenomena. Quantities, in turn, may hold other Quantities or values (numbers or strings). Higher-level data models, which associate or define meanings to various quantities (such as velocity or position), can be built from QML quantities. The higher-level data model (XML) schema that inherits from QML may be understood, and its instance documents may be parsed into QML documents and objects by the QMLReader.
The poldek is an RPM package management tool which allows you to easily perform package verification, installation (including system installation from scratch), upgrading, and removal. Package dependencies are automatically handled, so if you try to install a package that needs others to be installed, it will download all needed packages and install them. It can be used in batch (like apt-get from Debian's APT) or interactive mode. The interactive mode puts you into a readline interface with commandline autocompletion and history, similar to the shell mode of Perl's CPAN.
mkpkg is a small toolkit for automatically building Slackware or OpenLab packages. It should work on most packages that contain a makefile. It follows Slackware standards and is intended to build packages acceptable for linuxpackages.net. After you type the description, it generates a correctly formatted slack-desc file and logs configure options.
Swbis aims to implement the POSIX packaging standard with useful extensions. Working utilities include swpackage(8), swverify(8), swcopy(8), and swinstall(8). GPG/PGP signing and verification of tar archives is supported as well as an installed software catalog form that allows direct use of gpg(1) for verification of the GPG signature in the package database. swcopy and swinstall are network transparent by direct use of SSH and support multiple SSH hops for easy access to hosts behind a firewall. Neither has to be installed on the remote target host.
The "dpkg" suite contains the programs which handle Debian (.deb) packages. It was developed on Debian GNU/Linux but can be used on all Linux distributions and most Unix systems. The "dpkg" command can be used to install, remove and manage .deb binary packages, and it maintains a package database which gets updated on changes. It is also a front-end to the low-level "dpkg-deb" tool, which is oriented towards manipulating archives. However, the primary interface to dpkg is the "dselect" program, which is used to get and display packages for the user to select for (de)installation.
deb-install is a command line tool that can install or show information about packages and files in several different formats. Whenever a program is installed using deb-install, it is converted into a .deb package beforehand, and thus can be removed with a simple "apt-get remove <name>". It currently supports apt-get, .deb, .rpm, .dsc, and .tar/.zip (source archives). Compression via gzip or bzip2 is handled automatically. If a needed tool is missing, deb-install asks whether it should install it.
