+.B dryrun
+With the \fBdryrun\fR option, pppd will print out all the option
+values which have been set and then exit, after parsing the command
+line and options files and checking the option values, but before
+initiating the link. The option values are logged at level info, and
+also printed to standard output unless the device on standard output
+is the device that pppd would be using to communicate with the peer.

+.B dump
+With the \fBdump\fR option, pppd will print out all the option values
+which have been set. This option is like the \fBdryrun\fR option
+except that pppd proceeds as normal rather than exiting.
