  50  *     If you modify this file at all, please set the above date.
  51  *     if_ppp.h is shipped with a PPP distribution as well as with the kernel;
  52  *     if everyone increases the FILEVERSION number above, then scripts
  53  *     can do the right thing when deciding whether to install a new if_ppp.h
  54  *     file.  Don't change the format of that line otherwise, so the
  55  *     installation script can recognize it.
