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