XAR stands for eXtensible ARchiver. XAR is a new archive format, library, and archiver to meet modern archival needs. It can archive Extended Attributes and ACLs for Linux, FreeBSD, and Mac OS X 10.4 systems and resource forks and Finder metadata on Mac OS X 10.3. XAR can extract files using either numeric (uid/gid) or symbolic (username/groupname) file ownerships, saving the hassle of remapping uids/gids to the correct users. Python bindings, Cocoa bindings, and a Finder Contextual Menu Plugin are available separately.
xfburn is easy to use burning software for the Xfce desktop environment (but will work with others). It uses libburn and libisofs as a backend. ISO files can be burned, data composition created, discs blanked, and DVD-RW media formatted and deformatted. Common burning software features not yet implemented are audio CD creation and disc copying.
yaDMS (yet another Document Management System) is a PHP-based document management system, with many features like a clipboard, conversion of mail to DMS, conversion from DMS to mail, zip & download, copy, move, multiuser, and full-text searching with support for various document formats.
