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