0release is a program to generate source and binary releases automatically. With minimal configuration, 0release will generate a source tarball release candidate, build it to create a binary archive, upload them to your Web server, check the uploads, and tag the release in GIT and update the version number. It can run unit-tests and custom actions, such as building documentation, etc. For Zero Install users, it can also upload a signed XML metadata file about the release, allowing these users to upgrade automatically. Releases are signed with your GPG key.
Chestnut Package Manager is a utility to handle executables and resource files in a transparent, platform independent, and relocatable way. Its concept is similar to Apple bundles and Java archives. It is implemented in Python. Chestnut makes it possible to invoke programs or obtain resources without knowledge of their absolute or relative path, making them accessible even after relocation of the package to another directory.
Nix is a purely functional package manager. It allows multiple versions of a package to be installed side-by-side, ensures that dependency specifications are complete, supports atomic upgrades and rollbacks, allows non-root users to install software, and has many other features. It is the basis of the NixOS Linux distribution, but it can be used equally well under other Unix systems.
PeaZip is a cross-platform file archiver utility that provides a unified portable GUI for many open source technologies like 7-Zip, FreeArc, PAQ, UPX, etc. Creates 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, and ZIP files. It extracts more than 150 archive types: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX, and more. Features of PeaZip include extracting, creating, and converting multiple archives at once, creating self-extracting archives, split/join files, strong encryption with two factor authentication, an encrypted password manager, secure deletion, find duplicate files, calculate hashes, and export job definitions as scripts.
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.
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.
DJWrap is an effort to create an open format for combining several MPEG audio streams into one, without losing information about the original files and without disturbing the stream with erroneous or misplaced data. To this is added MD5 checksumming of each individual substream as well as an extendable data format which will, to the furthest extent, provide both backward and forward compatibility. It also supports both DJWrap and AlbumWrap files, and therefore replaces ALBWtool, which has been discontinued.
The GNOME Structured File Library is a utility library for reading and writing structured file formats. Support for MS OLE2 streams is complete, as is zip import. There is also support for document metadata and some initial work on decompressing VBA streams in OLE files for future conversion to other languages. This library replaces libole2 and is used in gnumeric, mrproject, abiword, libwv2, koffice. It is also part of the AAF format.
