Where can I download KTeXShell?

The current version is 0.4.0, you can download the source tarball at
http://ftp1.sourceforge.net/ktexshell/ktexshell-0.4.0.tar.gz.

An alternate download you will find at the KDE FTP server when the package is approved there.

RPMs are available for the KDE1 version, thanks to Rex Dieter for providing them! You can find them here:

Source RPM:
http://download.sourceforge.net/ktexshell/ktexshell-0.2.3p2-1.src.rpm.

Binary RPM:
http://download.sourceforge.net/ktexshell/ktexshell-0.2.3p2-1.i386.rpm.

To actually build the program from the sources, save the archive to a place where you want to unpack it. Then do a

./configure
make
make install

Then restart your panel;KTeXShell should now appear under the applications menu.
