Libxslt is a C library for GNOME which allows developers to work with XSLT. It is based on libxml for XML parsing, tree manipulation, and XPath support. Also included is 'xsltproc', a command line XSLT processor. The library is written in plain C, making as few assumptions as possible, and sticking closely to ANSI C/POSIX for easy embedding. It should work on Linux, Unix, and Windows. Though not designed primarily with performances in mind, libxslt seems to be a relatively fast processor. It also include full support for the EXSLT set of extension functions as well as some common extensions present in other XSLT engines.
The primary aim of the Gtk+2 panel project is to provide a panel that reuses whatever is available (if it is not overkill) in the obvious way, such as subclassing GtkWidget instead of implementing applets, or by using a GtkBuilder file instead of defining a new format to customize the panel. This approach gives some additional advantages for free: you can use common tools in uncommon ways. Above all, you can use Glade to design your own panel. All the dependencies apart from GTK+ are (and hopefully will be) optional.
Notes is a small ViewKit/Motif applet that provides post-it notes for the IRIX desktop. It's designed to integrate with the toolchest, but it can be run from the command-line too. A "Notes" toolchest menu is included in the "chestrc.notes" file. Notes uses the file format of the excellent MS-Windows post-it note application called "Stickies".
Oboinus is X11 background previewer and setter. In normal working mode, Oboinus provides an interface that helps you to choose a picture to be set as the background. When the --restore option is passed, it sets the background that it has a configuration for and exits immediately (for use in .xinitrc/.xsession or your WM startup files).
The Syllable project creates a family of operating systems that form a network platform. Syllable Desktop is a complete desktop operating system that is exceptionally powerful, fast, and easy to use. It has its own kernel, filesystem, GUI, and applications. Syllable Desktop is based on AtheOS, is largely POSIX.1 compliant, and uses many of the GNU utilities. Syllable Server is a server operating system built to be similar to Syllable Desktop, but on the Linux kernel.
