Simple Perl Package Manager tracks the files added or deleted from a system by using "find". It can detect modified files using installwatch, make backups of modified or deleted files, and remove, list, or make a tarball of a package. It records MD5 checksums of all installed files and includes a script to verify them and check other attributes of a package.
Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Rather than having a full distribution come from a single vendor, it allows administrators and developers to branch a distribution, keeping the pieces which fit their environment while grabbing components from other repositories across the Internet.
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.
XPKGTOOL is a GUI front-end for pkgtools that allows you to manage, install, remove, and upgrade packages with ease, through a nice and user friendly X-based interface. It comes with a built-in update manager, called SlackGrade, that will help you to keep your Slackware system up to date, checking, downloading, and upgrading the system with the latest packages available from the main Slackware distribution sources on the Web.
mrepo (formerly known as Yam) builds a local APT/Yum RPM repository from local ISO files, downloaded updates, and extra packages from RHN (Red Hat Network) and 3rd party repositories. It takes care of setting up the ISO files, downloading the RPMs, configuring HTTP access, and providing PXE/TFTP resources for remote installations. It was primarily intended for doing remote network installations of various distributions from a laptop without the need for CD media or floppies, but is equally suitable for an organization's centralized update server.
pkt is a universal XML packet archiver. It can manipulate files for backing up documents, transferring them across networks, emailing them, and sharing them by other means (p2p etc). It uses plugin filters to do the job and handles virtually any format available if there is a plugin for it. It handles encryption, compression, conversion, parity checking, decryption, decoding, repairing, rebuilding, and other tasks using a universal file format (XML-based). By default, all pkt output is in 7-bit ASCII which is UTF encoded and is compatible with XML parsers. pkt files can be disassembled, reassembled, and repaired by hand if necessary. pkt also supports the use of 8-bit compressed XML packets for its archives using one of several compression algorithms. In general, pkt will try to use the best algorithms available.
gnome-pkgtool is a GTK+/GNOME front-end to Slackware package management tools (pkgtool). You can install/uninstall/upgrade .tgz packages, build packages from source and install them, and inspect package content. It relies on the installpkg(8) and removepkg(8) tools for installing and uninstalling packages, and on checkinstall for building packages from source.
