  28  *     if_ppp.h is shipped with a PPP distribution as well as with the kernel;
  29  *     if everyone increases the FILEVERSION number above, then scripts
  30  *     can do the right thing when deciding whether to install a new if_ppp.h
  31  *     file.  Don't change the format of that line otherwise, so the
  32  *     installation script can recognize it.
