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.
BitRock InstallBuilder allows you to create easy-to-use multiplatform installers for Linux (x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.
W-Packager is a packager similar to dpkg that can be used by anyone to create and maintain Debian packages under Linux or other Unix systems. The aim of the project is primarily to have a workable version of a packager that can be compiled on many systems, including those that do not support fork(). At this time, W-Packager is used within UniGW. It can also be used under Linux.
UnZip will list, test, or extract files from a ZIP archive, commonly found on DOS and Windows systems. A companion program, Zip, creates ZIP archives; both are part of the Info-ZIP project. Both programs are compatible with archives created by PKWARE's PKZIP or Nico Mak's WinZip, but in many cases the program options or default behaviors differ.
Zip is a compression and file packaging utility for Unix, VMS, DOS, OS/2, Windows 9x/NT, Amiga, Atari, Macintosh, BeOS, SMS/QDOS, MVS, VM/CMS, and others. It is analogous to a combination of the Unix commands tar(1) and compress(1) and is compatible with PKWARE's PKZIP and Nico Mak's WinZip. It's part of the Info-ZIP project.
VAInstall is a multi-platform installer written in Java. Through a simple config file, it allows the packager to pick files and directories from various places on disk, and not only one root dir like other installers. The packager can completely reorganize the files and dirs on the destination host. He can choose the install mode for the destination host (graphic, xtra, text, or ANSI). VAInstall takes minimum space on the destination host; it does not write any large temporary files on disk, and supports easy and powerful uninstallation.
ZFolder2Product takes the contents of a Zope folder and creates a custom Zope Product, which then re-creates the entire folder contents when installed. The advantage of using ZFolder2Product over a normal Zope exportation is that the folder contents are saved in external files usable within a version control system like CVS. After re-importing the files, you can edit them using the Zope Management Interface and export them back to the filesystem.
