<question>
<para
>Why does &kde; use &Qt;?</para>
</question>
<answer>
<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>
</answer>

<question>
<para
>Why does &kde; not use gtk, xforms, xlib, whatever?</para>
</question>
<answer>
<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>

<question>
<para
>But &Qt; isn't free, is it?</para>
</question>
<answer>
<para
>It is! As of September 4, 2000, version 2.2 of the &Qt; libraries were licensed under the <acronym

>free software</quote
>.</para>
</answer>

<question>
<para
>Does &kde; have terminal emulators with transparent background?</para>
</question>
<answer>
<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>

<question id="CVS">
<para
>What is <acronym
>CVS</acronym
>?</para>
</question>
<answer>
<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>
