Oracle client is a simplistic Perl-based Oracle client that tries to mimic some of the functionality of PostgreSQL and MySQLs text-based SQL clients.

It is relatively simplistic, but much more useful than dbishell or sqlplus.

The project supports readline, history, desc, and various shorthand commands like d, , c, etc.

FlashUnity is a channel-based approach to an XML flash communications server and chat room.
Using the concept of channels and filters the FlashUnity server becomes extremely flexible and very easy to extend. Also, by using channels it is possible to run multiple modular functions within the same server.
Filters allow you to prefilter input for all channels or provide other functionality to all channels. This is a total rewrite of CyberSS, and the APIs and XML have multiple major changes. Each module, filter, and the chat client are in their own seperate PEAR package.
Enhancements:
- Room changes now work properly, and there are Uselist updates.
- This is the final release before 1.0.

Ksvn is a new Subversion client that looks like tortoiseSVN.
It can be used from the Konqueror context menu and replaces the standard KDE SubVersion menu. You can directly add, revert, and delete files from the commit dialog with a files context menu.
Installation:
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 a while. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Type `make install to install the programs and any data files and documentation.
4. You can remove the program binaries and object files from the source code directory by typing `make clean.
Enhancements:
- The possibility to choose a file when adding a directory was added.
