<para>&Qt; is a very sophisticated toolkit that provides everything that is needed to build a modern user interface. &Qt; is written in C++, thus allowing object-oriented development which ensures efficiency and code reuse in a project the size and scope of &kde;. In our opinion there is no better toolkit available for &UNIX; systems and that it would have been a grave mistake to try to build &kde; on anything but the best.</para>
<para>There are a number of toolkits available. To provide a consistent user interface and to keep used resources such as memory to a minimum, &kde; can use only one of them. &Qt; was selected for the reasons mentioned above.</para>
<para>It is! As of September 4, 2000, version 2.2 of the &Qt; libraries were licensed under the <acronym>GPL</acronym>, thereby fulfiling all aspects of <quote>free software</quote>.</para>
<para>Yes and no. &konsole; has the ability to simulate transparency by redrawing the background of the window inside the &konsole; window. This gives the illusion of transparency, but if you place &konsole; on top of another window, the transparency is lost. <ulink url="http://www.eterm.org">Eterm</ulink> should work fine under &kde; if you desire more complete transparency.</para>
<para>Create them using your favourite image manipulator, for example, <application>GIMP</application>, or the <application>&kde; Icon Editor</application> and put them in <filename class="directory">$<envar>TDEDIR</envar>/share/icons(/mini)</filename> or <filename class="directory">$<envar>HOME</envar>/.trinity/share/icons(/mini)</filename>. </para>
<para>Simply click on the <guibutton>K</guibutton> button and select <guimenu>Logout</guimenu>. In addition, if you <mousebutton>right</mousebutton> click on an empty area of the desktop, you will be presented with a menu containing logout as one of the options. <note><para>Depending on your configuration of the &X-Window;, <keycombo action="simul">&Ctrl;&Alt;&Backspace;</keycombo> might also do the trick by killing the X server, but its use prevents session management and cannot be recommended.</para></note></para>
<para>We recommend to always use the latest stable release. If you don't, it will probably be difficult to get answers to your questions. If you have a problem with an old version, the answer will probably be <quote>Please upgrade and try again</quote>. Note that new versions also sometimes fix security problems.</para>

<para>It stands for Concurrent Versions System. It is a version control system and is based on <acronym>RCS</acronym> (Revision Control System), but offers more functionality. It is used to maintain source code under development. It will keep multiple versions of things (handy if you broke something and have to back up and get a clean old version), and allows people remote access over the Net to pick up the latest source code and even to check in new files if they have permission. It is also open source (you pay for support if you want it), and since it is free it is the system of choice for people writing more free products, such as &kde;.</para>
<para>Fire up your <application>&kde; Control Centre</application>. It comes up with an Info Screen including the version of &kde; The &kde; version is also included in the application's <guimenuitem>About</guimenuitem> dialogue. </para>
<para>You can use the &kde; libraries to write <quote>commercial and closed source</quote> as well as <quote>commercial and open source</quote> software. If you write open source software you can use the &Qt; free edition. But if you write closed source software you may not use the &Qt; free edition; you need to obtain the &Qt; professional edition from Troll Tech. </para> <para>If you want more information, please contact <ulink url="http://www.trolltech.com">Troll Tech</ulink> directly.</para>
<para>Yes. But future versions of <application>LyX</application> will be &GUI; independent. Check the progress of the various &GUI; frontends <ulink url="http://devel.lyx.org/guii.php3">here</ulink>.</para>
<para>You might want to subscribe to the various &kde; mailing lists available, especially kde-cvs, which lists all commits done to the &kde; <acronym>CVS</acronym> repository. Check <ulink url="http://lists.kde.org">http://lists.kde.org</ulink> if you want to read without subscribing.</para>
