For instance, some programs can be compiled with gtk-support, or with qt-support. Others can be compiled with or without SSL support. Some programs can even be compiled with framebuffer support (svgalib) instead of X11 support (X-server). Pick your flags by selecting them. Your profile already set some of the flags, but you can override them if you wish. center 0 True True automatic automatic True 2 True Flag True Description 1 2 1
