PekSystray is a system tray dockapp similar to the GNOME notification area applet. But its designed for any window manager supporting.
Installation:
The `configure shell script attempts to guess correct values for various system-dependent variables used during compilation.
It uses those values to create a `Makefile in each directory of the package. It may also create one or more `.h files containing system-dependent definitions.
Finally, it creates a shell script `config.status that you can run in the future to recreate the current configuration, and a file `config.log containing compiler output (useful mainly for debugging `configure).
It can also use an optional file (typically called `config.cache and enabled with `--cache-file=config.cache or simply `-C) that saves the results of its tests to speed up reconfiguring. (Caching is disabled by default to prevent problems with accidental use of stale cache files.)
If you need to do unusual things to compile the package, please try to figure out how `configure could check whether to do them, and mail diffs or instructions to the address given in the `README so they can be considered for the next release.
If you are using the cache, and at some point `config.cache contains results you dont want to keep, you may remove or edit it.
The file `configure.ac (or `configure.in) is used to create `configure by a program called `autoconf. You only need `configure.ac if you want to change it or regenerate `configure using a newer version of `autoconf.
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system.
If youre using `csh on an old version of System V, you might need to type `sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Optionally, type `make check to run any self-tests that come with the package.
4. Type `make install to install the programs and any data files and documentation.
5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean.
There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
Enhancements:
- Complete reorganisation of the interface and code.
- Support for an unlimited number of icons.
- This release will only allocate necessary memory.
- It automatically creates another dock when the first one is full.
- --width and --height are available, superceding --vertical and --square.
- --multiple is the default now; it has been removed and --no-multiple added.
- A bug where some applications (grip, castpodder, etc.) had their icons at 0,0 has been fixed.

With AllTray you can dock any application with no native tray icon (like Evolution, Thunderbird, Terminals) into the system tray.
A high-light feature is that a click on the "close" button will minimize back to system tray. AllTray works well with Gnome, KDE, XFCE 4, Fluxbox and WindowMaker.
Enhancements:
- added "Stop" to the xmms menu. requested by me ;)
- get the gnome theme file by reading "XDG_DATA_DIRS". usefull if gnome is not installed in "/usr..." bug reported by Laurent Hilsz
- fixed shortcut bug. report and patch from Travis Hartwell
- fixed segfault which occur if apps where closed with "FILE->QUIT"
- fixed tooltip location with 2 panels on top. reported by Christer Edwards

SynCE-KDE is a Windows CE / PC connection service application like ActiveSync. It consists of three sub-projects: a full-featured KIOSlave for browsing the Windows CE device (RAPIP), a panel applet for accessing and synchronizing the device (RAKI), and a daemon which listens for device connections (VDCCM). This package contains the development files to develop synchronization plugins.
Main features:
RAPIP
- copies files and directories via drag and drop to and from the PDA.
- is capable of handling mime-types.
- supports more than one connected device simultaneously.
RAKI
- also supports more than one connected PDA at once.
- knows how to handle PDA partnerships.
- uses a plugin-architecture for synchronization. Two synchronizer-plugins are already implemented:
- Synchronizer for PDA-Contacts and standard KDE address book synchronization.
- AvantGo synchronizer.
- creates a NAT-Route for your PDAs to the outer internet.
- supports configuration of passwords, NAT routes, and synchronization settings per device.
- installs cab-files on the device - you just have to drag them over the system-tray or right-click on a cab file in Konqueror.
- lets you manage the software installed on the PDA.
- displays system information and power status about the PDA.
- starts programs on the PDA.
- answers password-requests of PDAs automatically.
- notifies about connections, password requests and disconnections of PDAs with sound.
VDCCM
- is responsible that RAPIP and RAKI can communicate with more than one PDA simultaneously.
- creates an individual "active_connection" file for every connected PDA.
- the names of individual "active_connection" files are either the PDA identifiers or the ip-addresses assigned to the PDAs.

Fluxbox Tray Menu is a little tray menu for use with the Fluxbox window manager. It creates an icon where you can reach your ~/.fluxbox/menu menus.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type sh ./configure instead to prevent `csh from trying to execute `configure itself.

Enhancements:
- Some memory corrupted messages were fixed.

Feedn Read (FnR) is a free Java based open source newsfeed reader. It is powered by the Sun ROME syndication framework and therefore supports all current formats (RSS 0.90, 0.91, 0.92, 0.93, 0.94, 1.00, 2.00, ATOM 0.30 and 1.00).
It disposes of an intuitive, fast and responsive user interface using eclipse technologies, i.e. JFace and SWT. Thus it combines the platform independent Java world on one hand with a fast native user interface on the other hand.
Main features:
- Multi threaded application environment
- Multi language support (german and english attended at the moment)
- Multi tab style reading
- Tree based favorite management
- Newsfeed retrieval and update
- Newsfeed aggregation
- Scheduling for automatic newsfeed retrieval
- Easy news filtering
- Easy favorite filtering
- Archive support (recognizes already read news)
- Newsfeed caching support
- RSS enclosure support
- Podcast support
- System tray support
- System tray notifications
- Internal web browser
- OPML import
- OPML export
- Customizable interface
