Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.
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.
wget can be used to download a Web site, with all pages referenced by the originating one, but it saves all pages in a directory tree (or single directory). The intention of web-archive-creator is to join the power of wget and the usability of the .war format, which Konqueror is able to browse. The Web ARrchive format is simply a tarred and gzipped file containing the Web files. The web-archive-creator script performs the download with wget and writes an index.html linking to the starting pages/URLs wget fetched.
Japt-Proxy is a fast and reliable caching proxy for Debian's APT system. It is intended for environments where several Debian systems have to be kept up-to-date and downloading the same files over and over again from the Debian mirrors is undesirable. Even with high volume internet connections, it can dramatically reduce the time required to install or update Debian on many machines.
PHP Tarbackup is a simple class that allows backing up an entire Web site. It automatically works around timeout limits by splitting the job into multiple requests, allows tarball archive creation and updates, and comes with the Veloce script, which is very useful to automatically unpack tar.gz archives remotely and skip long waiting times due to FTP uploads.
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.
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.
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.
