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.
