In order to use anything but the most primitive functions of ATM,
  several user-mode programs are required to assist the kernel. These
  programs and related material can be found via the ATM on Linux Web
  page at http://linux-atm.sourceforge.net/
  
  If you encounter problems with ATM, please report them on the ATM
  on Linux mailing list. Subscription information, archives, etc.,
  can be found on http://linux-atm.sourceforge.net/
