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