Is newly arriving and still being installed on sourceforge.
Please note the packaging still being written and the installation script, check_xdm, is thus in a state of flux.
check_xdm will be for installation (from packaging system) and for finding and fixing problems that occur after installation automatically (like lpd's check_pc except it can also fix most any problem that directly effect xdm's operation).
check_xdm is mostly complete but, again, is not finished and may have bugs. Also, the user interface will likely change dramatically to accomodate the format packaging systems expect.
