'''K3b''' is one among the '''most used Linux CD and DVD burning tools'''. The program does not write optical media per se, but it provides an easy graphical interface to widely used Unix command line tools: cdrecord, cdrdao, mkisofs recently renamed in genisofs and growisofs. Moreover K3b supports many codecs and external filters enabling the analysis of audio CD and VideoCD, the extraction and format conversion of the content. The tool can perfectly integrate with the '''Trinity Desktop Environment''' in spite of being optional and untied to the desktop environment.

The burning program was included in Slackware many years ago. A build script exist and can be updated and integrated for TDE distributed K3b release. K3b uses '''autotools''' to build as it has not been ported to [http://www.cmake.org cmake] yet. The following rules were applied when compiling the package to ensure a clean build:
