It's a bit modified installjammer project, regretfully not maintained now.
Changes
The changes are:
changing colors in Themes/Modern_Wizard/Common files
commenting out tk_setPalette line in gui-unix.tcl
alited.mpi (for Linux) is added to tests, just to share
These changes make the installjammer to be more usable in the dark themed KDE (otherwise not usable at all).
Still, even more important is that the resulting installers look fine in the dark themed KDE.
